The mitochondria is the power house of the cell
Have u heard the movie zoom by barry allen

I keep coming back just for the 3:44 "THAT FIRST EUKARIOTE WAS RICH"... watched that section over a thousand times now
Now I am doing what I did
Man ur comment is 3 years old
Too late
A better time to skip to is 3:45
Thanks for the time stamp 😂
It feels like one of those scenes in videogames where a character does something so out of place and so out of character you admire it.
Showing ATP as a currency was a great decision. Nicely done!
In our NCERT textbook also, it is mentioned as Currency
I clicked at the video for the thumbnail. I am not disappointed.
Well...
Seeing as ypur dollar bills are really just a rough representation of energy, portraying ATP as currency would be the most accurate layman's depiction
A lot of people are asking why I said "it happened only once" and then "what about chloroplasts?" so just to make sure this is extra clear: This video focuses on mitochondrial endosymbiosis, the one event that let complex life become possible! The chloroplast came later on (but I mention them in the video anyway)
+It's Okay To Be Smart Only if people would pay attention to the video.
+It's Okay To Be Smart.
The chloroplast go back to a SECOND event of endosymbiosis that lead to the evolution of plants! And the chloroplast have a very similar function, as they also produce energy (Photosynthesis instead of Glycolysis).
So it is wrong to say "it" heaped only once.
Also, it is defently not the most Important step for life. Many people say that Bacteria dominante the planet, and indeed no animals nor plants would exist without bacteria. If you insist: the endosymbiosis of mitochondira might be the most important step for "complex" life.
+It's Okay To Be Smart Hey! I was wondering if you could make a video about Veganism sometime down the line? The topic is really on a roll and I'm interested to see the science behind it!
+It's Okay To Be Smart So the most important moment in life was a collision between two bacteria...AWESOME! :D
This just in (well, more or less): Scientists discover microbe without any trace of mitochondria in Chinchilla gut - www.npr.org/sections/health-shots/2016/05/12/477691018/look-ma-no-mitochondria
Cool stuff.
Maybe if I eat a cat and don't digest it, I can use it to produce more energy!
+Bluespheal dame. it is a good idea but because of how we reproduce it would be impossible to included cats as are symbiosis friends for our latter generations
Wanna watch me try?
+Port Kapul A dog then, I bet those cold hearted cats won't help us evolve
+Bluespheal
Try eating an elephant without digesting it. You'll get a lot more energy out of an elephant than out of a cat.
If I ate Schrodinger cat would I get more or less energy?
I literally learned more about cells on a 6 minute video than i did in 12 years of school
You guys need to realise that it's not just learning you fcking exists because of it and your teacher too so please understand reality
The mitochondria is the powerhouse of the cell.
darkk mane?
THE POWERHOUSE OF THE CELL! *cue thunder*
Nolan Thiessen yes, yes it is.
A biology joke for people who know the currency in Britain.
A biologist goes into a bar, order one pint of adenosine triphosphate.
Bartender says "That'll be ATP" (80p)
+Kishore Shenoy
I know some Americans will say
"That doesn't make cents"
lol
Why....
😂😂
+Kishore Shenoy this is the real punchline. made me giggle
Bravo, hahaha
An event in the history of life so important, it's OVER 9000!
Can't wait to see all the science you do in your I DID A SCIENCE shirts!

3:40 I can only imagine the amount of fun the production team had when coming up with a joke to go here:
Scientist #1: How about "And it had THE POOOWEEERRR!!!"
Scientist #2: Nah, we should say "And it could go to infinity AND BEYOND!!!"
Scientist #3: Actually, this would be the perfect time to say "And it had UNLIMITED POOOWEEERRR!!!"
Scientist #4: How about "And it's power level was OVER 9000!!!"
Other scientists: ...Actually, that might work.
Just a tiny nitpick, not that it makes a huge difference to the overall argument: it is possible that many examples of endosymbiosis have taken place in the last couple of billion years, but any niches they could inhabit were already taken up by organisms (prokaryotes or eukaryotes, it doesn't really matter which) that were very well adapted to them, so new endosymbiotes die off whenever they form, leaving no trace.
+Mr Schrödinger - I am the one who reviews. It'd be an interesting possibility. My guess would be 'No', since we see many examples of 'convergent evolution' and shred niches and organisms occupying the same niche in different environments.
We even have many cases of bacteria residing in animal (often insect) cells, though not reduced nearly as much as mitochondria are.
"Two prokaryotes branches diverge on a yellow wood....."
and then later reform into eukaryotic life forms
I honestly love this guys video's. Not only do you learn but he makes it fun to do so through his videos.
2:52 "an event so rare, it only happened once in life's history" |Later| 3:59 "Some of them gulped up a second bacterium"
The rare event is the event of a prokaryote gulping up another prokaryote. The fact that the eukaryote got a second bacterium that became plants is less impressive because we already know that cell was special since it got the mitochondria already.
3:42 CRACKED ME THE FUCKED UP
BEST CHANNEL!
Thank you, Dr. Joe!
Keep it rollin'!
Isn't it possible that this has happened more than once, possibly even many, many times but they didn't have the chance to reproduce?
+BlakeMcTavishe Possible but extremely unlikely, it's such a big advantage...
I think it did happen more than once, but even if you are an ATP milliobaire, you can still get eaten by other cells... so... I guess some of these cells were just very unlucky
+BlakeMcTavishe The main reason we think it only happened once is that bacteria and archaea interact all the time today, and yet there's no evidence of this kind of thing having happened again. It just seems to be so improbable and unique that "once" is the best answer we have for the mitochondria. Now ask yourself: What does this mean for the possibility of alien life?
+It's Okay To Be Smart
It means that aliens are likely to be really chill, stoner-like beings who'd say "whoa, whoa, whoa, dude! Not so fast" to pretty much everything humans do.
+myky992 true, but if it happened after our common ancestor was allready estabelished, it would'nt be such an advantage. In fact a new type of cell during that time would have a lot of catch up to do! But that is just a guess... :)
The most important moment in history and I missed it
You can tell everyone amazing stories from your great great great great great great parent, though
Always love your videos! I struggle with biology a lot, but your videos always help me learn! I have my bio exam on Monday so thanks for uploading this!
Life is better together. Nice to see it spelled out like this. Hello from 2021!
From the thumbnail I thought it was anime that was important
it is
anime is the cancer of this society, so…… no
+Arad Seyed anime is just another form of entertainment. Don't see reasons to hate it.
+Arad Seyed

and isn't it?
beautiful story,now I can sleep
when I have a kid I'll tell him/her this story before sleep
John Cena, over 9000, I wonder what meme you're going to do next...
EVEN SPEEDWAGON IS AFRAID
I just got to this part in "The Vital Question", the book you recommended in your last video, this was a great visualization of what was in the book. Thanks for your book recommendations and your videos :)
This is one of my favorite topics! Thanks for the video!
Yo I got the cell right. I just went with "This one looks like a messed up burger"
+Cutman3030 I got them all wrong when he said they were wrong
3:58 Hey so it didn't happen just once !
I WISH school just showed your videos at school. Myhealth teacher tried to teach me this in a whole quarter and I understood absolutely nothing.I watched like all your “it’s ok to be smart” videos and understood everything SO much more easily and more fun too.I love learning but the school system makes it so dreadful.Its sad honestly,but hey at least I’m learning.
This channel is beyond awesome.
you said it only happenned once, with mitochondrias, but... chloroplastos? Don't they come from endosymbiosis too?
Yes
RemySML And wouldn't that make the event have happened twice?
He mentioned that in the video
He's saying the event only happened once
So all the choroplasts and mitochondria came from this endosymbiotic process all those billions of years ago in a short space of time
Yaaay! I picked the right cell! Where are the other geniuses? I want my medal!
I want a cookie
I love this channel so much.
You are litteraly following all the stuff my class is learning
Perhaps this is the answer to the Fermi Paradox. The reason we haven't come across any intelligent alien life is because the chances of cells forming mitochondria are so improbable as to be basically nonexistent. Life on earth just happens to be one of the few exceptions in the entire universe.
How do you know the odds of cells forming mitochondria like organelles is rare for all we know it's very common and it just took a long time on earth
+Aaron Smith
He just said in the video that it is likely to have happened only once.
+Brandon Hall
The universe _is_ infinite and this has happened an infinite number of times.
The only question is: What's the closest place to ours that _currently_ has "complex life" from our perspective?
+Brandon Hall once in earth, the only place were we know life ever existed. We don't know what are the chances of it happening, and in a galaxy billions of years old with billions of stars, we don't know the chances of it happening somewhere else.
+MyChico333
True. I just thought this could be one possible explanation for why we have yet to find any other intelligent beings in the Universe.
It probably happened a ton of times, most just didn't make it.
Hey Joe! Smart people here! love your content keep up the good work!
Endless forms most beautiful... I love that album!
The most important moment in life, is when life began. No one can argue with that.
*a committee discusses this new idea*
I will argue with that. Dinosaurs > Single celled organisms. BOOM!
Jason Stackhouse Interesting points, but have you considered....no?
i've considered no, but I raise you a yes, in it's place.
But it began (probably) thousands of times.... And there was probably so much orizontal gene transfer that almost every (RNA) sequence could be passed around (and this theme probably continued with the invention of DNA albeit at slower rate until eucaryiotes came around).
Very interesting, I see applications for the Fermi paradox. Love the video c:
You always do a fine job, but this one is truly most excellent.
Damn it. How I wish I had internet and this channel back when I was in school. I learn so much with a simple video
The Mitochondria is the powerhouse of the cell, wheres Darkk Mane?
Well, it's a pretty brave statement to claim that it only happend once (and with such a certainty). If it happened 100 times, how would you spot any difference in the outcome?
Becuase the mitochondria is the same in all eukaryotes.
I really liked how this one was presented. Thanks for this!
I was excited about this video, but shocked when it wasn't about the finale episode of Dawson's Creek. I mean, all life on earth is pretty nice, but the love between Pacey and Joey is beyond quantification.
MITOCONDRIA!!! I KNOW WHAT THAT IS!!! IT'S THE POWERHOUSE OF THE CELL!!!!
+Fangirl *Mitochondria
+RandomGuy *Mitochondrion. Mitochondria is plural C:
Shak Pherze yeah, but I'm not a grammar nazi. There are more than one mitochondria per cell (iirc should be thousands) so you should be correcting the rest of his sentence instead to be plural.
RandomGuy I apologize for my spelling error and grammar error. Also, the correct pronoun is she(hence the FanGIRL.) (Also this sounds a lot more aggressive than it's meant to be, so keep that in mind. I just didn't know how else to word it.)
Fangirl Sorry about the mistake, I don't really look at usernames most of the time, and for some reason I default to 'he' when I talk. I know some girls can be rather picky on the subject, so thanks for being chill about it.
I picked out the human cell first try!!!1!
I knew this happened, but I didn't know it was so improbable!
0:12 - 'So you want to be multi-cellular¿!' By Dr R. Kaya and the 'Bestceller Section' had me LMAO.... 😂😂
I loved the episode. I'm a little curious if this episode drew inspiration from radiolab (they had a podcast talking about this very subject just a couple of weeks ago)? If anyone else wants to check it out the title was cellmates and it basically covers the same event just a little more in depth (they had 32 minutes to work with).
if you guys did that's awesome! If not, that's awesome too. What with two different programs just happening to think about the same topic and finishing their work around the same time
+Evan Sabourin Actually I was literally getting ready to shoot this when that Radiolab episode came up on my feed! It's crazy that we were both working on the same topic at the same time. I love that episode of Radiolab, one of my instant favorites
+It's Okay To Be Smart can saitama training work. please make a video for it ●_○
@@besmart lol watched this 6 years later
Let's talk about the hypothesis of the origin of the nucleus
+Elias McComb Oh man, that's some *DEEP* biology. Genetic invaders, mobile DNA parasites… might have to save that for when I make a "Deep Biology" channel or something (but I did my grad work on similar stuff, so I actually love this story)
+It's Okay To Be Smart I just watched your Ebola video, are you still going to do that zoonosis video, I'm curious about it.
@@besmart awwwwww please please make a deep biology channel i like so much these topics but almost never find scientific articles about them.
5:42 Ahh, Endless Forms Most Beautiful by Nightwish... Loved that album to death. I even have the tour edition of it. (I know that's a snippet from Richard Dawkins, but he narrates that quote on the album, too.)
Cool, you did mention it. I was hoping you would go over that at some point the second I finished with the previous video, and you did. Science Delivers.
the word "exponentially" has a completely different meaning than how it's used at 2:05
I didn't expect such a mistake in this channel...
You should work for them
From my understanding of the word, he's correct. The grow of the volume is exponentially connected to the grow of the area. Isn't that correct?
It's actually a cubis relationship if you can call it that, because when you double the radius, the volume increases by the factor 8
DerTaktikFuchs Which just confirms what I said, doesn't it? I don't want to be an arsehole, but ^4 is an exponent.
+Tomasz Antochów This is not what exponential means. You can raise everything to a power without changing it (to power 1) but this doesn't make it exponential.
From wikipedia (Exponential function):
"Exponential functions are uniquely characterized by the fact that the growth rate of such a function is directly proportional to the value of the function."
The volume grows as the area^1.5 so it grows based on the area (not based on the volume).
3:45 So everyone's ancestor is Bill Gates?
Yep even your pet!🙂
Even i know something that never happened since the big bang let alone 4 million years..
the thing is "Iam commenting on this video"...trust me, this happened just now.. and congratulation readers for witnessing this phenomena..
This channel has taught me more important stuff than my school
The first love story....
this could have been an answer to the fermi's paradox
I like how you explain science. You explain it in a funny way while teaching
I've been looking for this video for 4 years
all these memes... what time to be alive
+UniQuE TV You could say... the time is Just Right. 👌 (-_-) 👌
+1234kalmar Is that what I think it is 👀
Tracy HeadCasey Pacha? :D
1234kalmar 😂👏
Good lord.. The hair game.
your videos are amazing and I love the fact to be curious
The presentation is phenomenal
Plural = 'mitochondria', singular = 'mitochondrion'!
There definitely needs to be an episode about the grammar of scientific words derived from Latin & Greek.
+Phil P I know... I hate it when people say "specie", as if it were a word-or "Homo sapien"! I strongly suspect that "bicep" used to be a non-word as well, but it looks as though that one has been added to dictionaries now.
Thumbs up if you picked the correct cell
Not very many thumbs up there
I was undecided between the human cell and the yeast cell so can I claim half a point?
0:55 I GOT IT!!! My science knowledge has never failed me!
2:50 Yeah I know that even, one product inside and one escape. That one times smart choice make a HUGE different.
(Looks at the thumbnail)
Yes! I am not the only person who thinks that creation of anime was the most important thing to happen EVUR!
(Watches the video)
Ohhhh...
Well...
Then creation of anime is the secon most important thing.
Yup
There are many who beg to differ, and claim it is the most infamous event in history.
+Revolver Papyrus Anime was a mistake
We have ice cream too so maybe anime was the third.
Combinemon
We have Metal Gear Solid, so it's the tenth at most.
⚠If there's no ruling out performing _Artificial_ Endosymbiosis in an ecosystem that was all those years ago, there's nothing that rules out that *Aliens* could have started life on our planet... 🌍
MAK but you can't prove that aliens did it either...
man I love your videos. Tyvm for making them! My new boredom filler instead of gaming 24/7 gg
Life and organisms are amazingly beautiful.
force them to do that again
Funny video. But how do scientists know this happened only ONCE?
I can imagine scenarios where this could have happened a billion times all over the place with the same outcome. Maybe half a billion symbiotes died before they amounted to anything and the other half finished the job.
Or maybe this symbiosis happened but all of these new cells died and then 475.521 years later it happened again but this time they survived. Is there any proof my theory could be wrong?
No you are absolutely correct it very well could have happened many times over and for my money I think it's more likely it happens many times and they died out for some reason than it only happening once and that one individual surviving
+2nd3rd1st It's definitely right, we've seen endosymbiosis start... and rapidly fail. Entire families of bacteria like wolbachia specialize in infecting cells and passing themselves along through generations. Not parasitic examples are more rare and seem only to involve animals (that we know of.) but are increasing the more we look. But nothing has approached mitochondria in how thoroughly intermingled the two partners have become.
You heard it here kids. Work together, and you will create unbelievable things!
+artfx9 And one guy will get all the benefits while the other is reduced to a single task for the rest of eternity!
Gareth Dean That is usually how businesses work.
Love you man!!
That's one heck of a claim. Do yo have any evidence of that? I mean. A completely new mitochondrial life form could have come into existence last Thursday. But because it's a gazillion years behind it wouldn't be touted as new and exciting. It would be lunch for something more advanced and you'd not see it.
Search for "endosymbiosis: in Wiki and see the evidence. My favourite is that they have a genome! If it was just a bit of machinary inside the cell they wouldn't need any genome, but the mitochondria wee see has a genome and that genome is also similar to other kinds of bacteria which suggests a relation between the two.
Mortadha Alaa I'm not saying that it didn't happen. I'm questioning the claim that it happened only once.
+Lucid Moses
I guess the claim should be: all eukaryotes we recognize today as separate species have one common ancestor. You are right, of course. But it's kinda 'trivially' right.
Shangori from earth only point of view and your not interested in science then maybe. But if you try and work on the idea of odds of life being out there in the universe then that detail is very very important.
+Lucid Moses Scientists have looked and looked for another event more recently, and they haven't found it. It really does seem that mitochondrial endosymbiosis only happened once, or in one class of early cells (or if it happened more than that, they didn't survive). We just don't have any reason to think it's more than once, so Occam's Razor applies…
I first thought this was going to be about the Battle of Hogwarts
Our ancestral eukaryote getting rich got me :) Nice video doc, you have my sub and my like!
the editing on this video is on point
How do we know this
We just guessed.
+Bartu Muzo
Science.
we have faith
Paul Jones i already know that . But how exectly
+Bartu Muzo
Because Mitochondria actually have their own DNA that is not related to the DNA in our Nucleus. The DNA inside the Mitochondria had to have come from somewhere and it is thought to have been from another bacterium.
'It's over 9000!!!!' *break glasses* not 'It's over 9000!!!!' *get cute eyes* 😕 Never seen Dragon Ball Z?
+PamdaWolf In the video as in that would have been a much more appropriate choice 😁
+Jonathan Ouwens I thought about that but I didn't want to have to buy new glasses, guys
As a mathematician, I feel obliged to point out that non-linear growth is not the same as exponential growth. What you describe is the square-cube law, which is just a simple polynomial.
Good video. For those of you who, like me, are not biologists but have an interest in exploring the origins, mechanics and fascinating consequences of the eukaryotic 'revolution' and the role of mitochondria, I can recommend Nick Lane's books (the one on mitochondria or his most recent ' The Vital Question').
Where does God cone in?
**burbs* Mm, there is no God, Mr Rexton. You got to rip that band-aid off now. You'll thank me later.
+Mr Rexton Science is all about proving and disproving things, and the existence of a god can't be proven or disproven.
This guys is teaching science, not religion. Whether or not you believe in him, God doesn't have a place in this science-focused video. There'd just be no way to back up any claims surrounding him scientifically.
+Κώστας Καραπαπαχατζηδιμιτρακόπουλος jeez Rick
+Κώστας Καραπαπαχατζηδιμιτρακόπουλος what's next are u gonna tell me that Santa and The Tooth Fairy aren't real
He comes in when the first human was scared by life and needed something that could help him.
3:40 if you are going to do a pointless "It's over 9000!" reference, at least do it right. Shout the line with rage, pull off your glasses and crush them in your fist, and if you must have "anime" eyes, make them less generic and more angular (like Akira Toriyama's style).
The rest of the video is excellent, but that painful part stood out too much to not go without comment.
more attention to detail than a PC gamer right here
+BallotBoxer I admit, I was a bit disappointed about that part too.
I guess you could say I did
*turns hat sideways*
not approve.
Yes!
in case that went over your head, it was a subtle joke making fun of people misusing memes.
Good job, great informative video my friend!
Great follow up from last weeks video! +it'sokaytobesmart
Regarding *I DID A SCIENCE*.
I'm assuming that most people with a scientific education behind them will have too much self respect to want this dreadful slogan emblazoned across their chests.
+Jack Sainthill I have a Ph.D. in molecular biology and it's like my favorite shirt
It's Okay To Be Smart
Yes, I said _most_.
I truly admire your achievement and, my having watched your videos, I've never doubted your scientific credentials.
Perhaps it's a cultural thing and the phrase sounds cool to a North American,,but _I DID SCIENCE_ just signals _stupid_ to me, over here.
Actually, even _I DO SCIENCE_ would sound better. At least nobody would wonder why you stopped.
Woah
+Jack Sainthill Its mostly for ironic comedy. Someone who is seen as smart [scientist] wearing a shirt with obviously bad grammar is ironic, and to some people that's funny, thus people wear it for comedy and not status. [Of course comedy is still a very subjective thing and people have MANY different preferences, but irony is a big source of comedy usually]
Eragon7
I, understand that, thank you, but the thrust of the irony is actually ambiguous.
A wearer of the slogan could be making the deliberately malicious claim that scientists are so stupid that they cannot even use basic grammar properly.
It seems to be just me but, although I understand the joke, I don't feel that it quite works. Sorry.
watched this video like thousands of times
everything needs to be explained to me like this
Wow. I love the channel
Excellent video
At 2:15: when you increase the size of a cell the volume grows with the cube and the surface with the square of the length. Length is x, surface is x^2, volume x^3. Exponential growth would be n^x.
Wow, a great explanation about endosymbiosis !
I am your great fan Dr.Joe Hanson. I watch your every video for my interest in Science and mainly in Biology.
