Dude never stop making these, You're bettering the world. Please keep going with science stuff, It's the most important! us anatomy and biology majors need you!
dude i had absolutely no idea what my teacher was talking about and neither does my class u summed up her whole 1hr lecture in 13min and made it sooo much simpler THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
your comment about taking it as a leap of faith really stuck me. I hated biochem for the main reason that i had to take everything in it as a leap of faith, and i didnt appreciate memorizing it. Thanks to your video i can finally understand it and not just memorize it and say it just happens. Thank you so so so much
Awesome work ! I think all biochemistry teachers should see these videos before they get out there to teaching. This is how explanation should be and not to confuse students or try to make the subject even harder.
Can't thank you enough. My Human Biology Professor is from Nigeria and has a very thick accent and reading the book can only do so much! Khan, you are my hero!
I had to watch this for a moodle day for my biology class (Moodle is a system that my school is privilidged to use, and we take a day off of school [about every 2 wednesday of the month] and do all of our work online, and I will say, this man can explain all of this better than any of my teachers ever could, and I will say, I think anytime I don't fully understand any concept that my teachers try to explain, I will come here.
The electrons in ATP around the phosphate groups are being pulled in a bunch of different directions and are therefore in high energy states. When a bond between two P groups is hydrolyzed, the electrons in the P groups can drop down to lower energy levels (closer to the nucleus). When this happens, energy is released. The difference in energy levels results in release of energy.
Just a clarification: phosphate is not on the periodic table; phosphorus is and is the element that would have 5 valence electrons. Phosphate is a polyatomic group which is shown in the molecular structure in the video, so it was probably just a slip of the tongue as with the centrioles and centromeres in the mitosis video... :-P Thought it was worth clarifying for anyone confused though.
It took mu chemistry teacher 2hrs to explain this n i still didnt understand it. U explained every thing he did n 15 minutes and more clearly. FCK paying 3grand a semester you tube you are my new teacher.
+Dearic Smiles right, ive been going to 3 hour biochem lectures for the last 8 weeks, and what the lecturer said in 3 hours, this guy has said in like 10 minutes
Dearic Smiles may be they didn't know it or didn't bother to tell you most teachers are dictionary of concept information only a few know what it really is.
I always look up youtube video's to explain the shit my Biology teacher couldn't explain in a week. This video was very useful. Thank you for sharing this with us. :)
I can tell this guy is trying to teach us "visually". Which is a great thing when he draws out, and explains everything. I would ace this dude's class if he was my teacher. :)
Wow I knew most of the stuff at the start but approaching the end I learned a few intresting things. This is so fascinating because i started lifting weights when I was 16 and fell in love with the science behind it. Im 17 now and I have had amazing results in the gym and its intresting to know what is actually happening. the world is just amazing I get teased for watching this for fun but I dont even care lol way better then mtv and drugs my friends are all into
@Ben. This is a subject for a more advanced course, but creatine is like a "shuttle" or "valet parking" for high energy phosphate (ATP). It helps move energy from intracelleular stores to the mitochondria. Eating it doesn't really do much for you, aside from placebo, but the water comes into play in order to protect your kidneys (your natural body filters) from being hurt.
thank you, thank you, thank you!!! I am in Biology right now and for some reason cellular respiration was confusing the shit out of me, but you make it so easy to understand!
Maan, really wished KhanAcademy was my teacher at school, all my current teacher mostly does is give us bookwork to do, then the day before the test, tell us the main points so we can cram.
WOW I have been looking for WHY and HOW does this break f 3rd Phosphate break off what breaks it off and why does it create energy... and here is the answer to number 1 how ie breaks off .... THANK YOU !!!!! I think I have spent a week looking for an answer and here it is... NOW can you show HOW IT IS THAT IT GIVES ENERGY ability to do ... what does it do,,, what does it maybe catalyze ???? ml bente
Thanks A lot! I always learn better visually and the concept of ATP was kind of looming over me because I got the rest of my material but this video helped ALOT! thanks for making it easy to understand ^^
Just a clarification: The energy is not released when the bond is broken. From the perspective of physical chemistry, energy is released only when bonds are formed. In the case of ATP, simply cleaving ATP is actually an energy investment - energy is only gained when the third phosphate becomes attached to another molecule. As an example, the free P may causes changes to the shape of an enzyme, which, in attaining a more energetic form, may facilitate the otherwise hefty amino-tRNA synthesis.
Energy is basically the ability to cause things to happen. In this case, ATP is storing energy in its chemical structure until it is required to fuel biological chemical reactions.
"When the phosphate is broken by hydrolysis, it can transfer a considerable amount of energy." that came straight out of the textbook. im not saying your wrong but now im confused lol
thuglife6161971 the textbook is saying exactly what he said in order for atp (stores energy) to transfer into adp (used energy) you will need h20 as the middle man. Hydrolysis - the chemical breakdown due to the reaction with water. Hope that helps 💓
Enthalpy (bond energy) has little to do with the energy transfer capacity of ATP, or any other biomolecule for that matter. Energy in to break a bond! It its all about entropy. P-O bond rotation is restricted by the negative charges. Resonance is restricted in the phosphates. Popping the phosphate off removes those restrictions, with a resultant entropy gain.
so where does atp energy come from, is it mined, gathered, hunted, harvested? all the above? what is the effect upon mother earth when we play with these bioenergies and what about disposal? this only looks at the technical side of things and not about the effects. it may make us smarter in some ways but at what expense?
@godsownphilosopher how is it that energy is released when bonds are formed? I can understand that it "costs" energy to cleave (good word, btw) a phosphate from its "comfortable configuration" (as a physicist, I might use the phrase "least potential state"), but it's hard for me to picture a release of energy upon bonding. What form does it take? Sorry for my lack of knowledge in physical chemistry :)
So, the phosphate groups store energy by making their electrons uncomfortable. Why is the adenosine necessary? Clearly there would have to be something there, so that other molecules could recognize it and the body could control it, but why adenosine in particular? The group would have to be consistent, since it is part of something intended to be a currency, but would it have to be adenosine? For example, could some alien biological system use something completely different?
Why does it have so much energy to give away? Is it because there is a lot (and takes a lot) of energy used by molecule to hold the negatively charged phosphates together and by breaking the bond there is a lot of energy released because new bonds formed are more stable and don't require as much energy?
Question; So adenosine triphosphate is composed of adenosine and 3 phosphate groups. & adenosone diphosphate is composed of adenosine and 2 phosphate group... & a hydroxyl group? Always?

Finally, someone who can put all this together to make some sort of sense! Thank You!!!
I wish schools implemented your way of teaching/learning and more professors taught like you; thank you so much, Mr. Sal & Khan Academy!!
i am in 9th grade bio, this helped so much. i love learning little tidbits like this. thanks for the lecture
hey me too lol

exacly!!

most teachers are dictionary of concept information only a few know what it really is.
Same here!
Because they're being paid to finish 10 chapters in a whole year, they can't teach you straight away

"Ooh. I wonder what colour he'll choose!"

To Be Frank This Is Far Better Explained Than In Crash Course Biology
Twenty Two Jetskis most definitely.... cc is boaring
Who knew it could be so simple? Thanks a lot, I'm not even taking bio anymore, but it's fascinating to learn about these things.
Thank you! Studying ATP for my Nutrition Coach certification and this really helped break down the information in a memorable way.
You're a good teacher, I wish you were in our school it would be so much easier to understand the biology
You, Sir, are a great teacher.
This was exactly what I wanted to hear. Kudos.
my AP Bio test is coming up and these videos have been super helpful!! Thanks!
Wow, wonderful!! I wish you were my teacher as well! Really great, clear, and explained simply :) Thank you!
nice work is done by khan academy for growing children's.... thanks to Salman Khan sir
Brilliant mate - wanted an explanation of the concep and i got it.
You are way better at explaining things then my current professor, I subscribe, please keep these vids comin!
Where would I be in life without Khan Academy... Universities watch out!
Hear hear!
u legend,u made it seem so easy,thanks a million u been a massive help :)
Your vids are wonderful! Soooo helpful!
I just watch them and I get it, while when I try to learn it from my textbook I won't.
Thank you!!! I'm preparing for my biology test this week. Bring it on! lol
I wish my bio teacher explains bio like you do! I wouldn't be struggling so much =\
great job, very helpful!
Thumbs up if you think the creator of these should receive the Nobel Prize.
My final is in a couple of days, and I finally understand this. Cannot believe it. THANNNNNNNNNNNNNNKS

Really good explanation !! Makes it all make sense to me !!! If I had your videos I would have passed several more classes in school!!
Thank you! I finally (and somehow unexpectedly) understood how energy is released.
thank you, thank you, thank you!!! I am in Biology right now and for some reason cellular respiration was confusing the shit out of me, but you make it so easy to understand!
I really appreciate this. could not thank this guy enough
You should teach all science teachers!!!! Incredible!!! Thanks
Thanks for sharing! This video helped me with my biology class! :)
I wish you were my professor. This really helped.
Am I the only one that comes here for fun, rather than school?
You are the one and only.
who the hell does that? O.o

Same bro!
No, you are not. I am here for fun too. It is interesting to see what we and life on earth are made of.
I just fell in love:D thank You!

THANK YOU!
you saved my life. literally.
Whaat 13 mins done already? damm u made it feel like 2 mins ur the best!
Mr.Sal, you're the best 🙌🍭✨
Awesomeeeeee!!!!!!
it made my alll concepts clear....
thakxxxx a lottttttt!!!!!!!
Love this vid... Keep on goin!! Very very helpful

Thnx thnx thnnnnnx:)!
"My analogies always break down at one point..."
LOL
Totally confident about my upcoming tests on ATP lol. Thanks!!
Really good explornation !!
i love your handwriting
May God Bless You Man
Thank you! you are a real blessing
ooo this links what im learning in chem (quantum energy) to bio!!
so where does atp energy come from, is it mined, gathered, hunted, harvested? all the above? what is the effect upon mother earth when we play with these bioenergies and what about disposal? this only looks at the technical side of things and not about the effects. it may make us smarter in some ways but at what expense?
haha i learned this in class :D. still awesome bro...
Could you explain the resonance stabiisation of orophosphate?
And why ATP is such a good phophoryl doner
Very helpful!
Thank you :-)
Hey, what does a muscle contraction cost? 80p...
Khan Academy is AWESOME!!!!
i love your writing
his voice is pleasing to my ear holes.
Hello, great video, helps a lot😊
You are my hero.
does the water molecule only react with the phosphate and did not bring the product?( to become one of the product?)
@godsownphilosopher how is it that energy is released when bonds are formed?

Where have you been all my life?
Antonio Climax on UA-cam... u never searched for it... duh
This would have been way more helpful to me a month ago! I'll need it for a final in June though... Thanks anyways Sal!
So, the phosphate groups store energy by making their electrons uncomfortable. Why is the adenosine necessary? Clearly there would have to be something there, so that other molecules could recognize it and the body could control it, but why adenosine in particular? The group would have to be consistent, since it is part of something intended to be a currency, but would it have to be adenosine? For example, could some alien biological system use something completely different?
i cant help but to listen over and over how u say "currency"... i love it . creepy, i know.
when muscle move it use K Na pump in the cell or ATP energy ? or it its related ?
Why does it have so much energy to give away? Is it because there is a lot (and takes a lot) of energy used by molecule to hold the negatively charged phosphates together and by breaking the bond there is a lot of energy released because new bonds formed are more stable and don't require as much energy?
really cool story bro
Sal you remind me of Ian Malcolm from Jurassic Park.
Question;
So adenosine triphosphate is composed of adenosine and 3 phosphate groups.
& adenosone diphosphate is composed of adenosine and 2 phosphate group... & a hydroxyl group? Always?
