- NDSU Virtual Cell Animations Project animation 'Cellular Respiration (Electron Transport Chain)'. For more information please see vcell.ndsu.edu/animations
Cellular respiration occurs in the mitochondria and provides both animals and plants with the energy needed to power other cellular processes. This section covers the electron transport chain.
This takes "The mitochondria is the powerhouse of the cell" to a whole new level.
Are you going to comment this on every electron transport chain UA-cam video? 2nd time today I see this same comment
@@alanzeblade928 those were the only two times I commented it
I don’t even remember I made this comment it was a year ago and I only did it twice so please don’t get mad at me
How could you make such an incredible video like this 12 years ago!? I've been looking for a good video and this was littrally the best one, Love it ❤️
Nice video, but lets be honest, I still have no idea what the fuck is going on
Same here
+Reagan Nelson exactly. this is the only part of cellular respiration that i do not understand at all
+MizzBalleriffic23 Really? I'm more confused on the Krebs cycle.
+Sir Hadoken ha they don't even call it that they call it the Citric Acid Cycle
+Reagan Nelson +Reagan Nelson Don't know if this helps but here goes: What you want =
ATP =energy = staying alive. So to make ATP we do the whole respiration
thing to extract energy in glucose. This is done in a few steps, First
Glycolysis, then Kreb's cycle, then Electron transport chain (What this
video is about).
We got 2 ATP from Glycolysis, 2 from Kreb's cycle. But that's really low, we need more. So we have this mechanism called Electron transport chain. It uses the stuff we got from Glycolysis and Kreb's cycle that's not ATP. They are molecules called NADH. They basically carry electrons, simple as that. So these NADH thingies go to this Electron transport chain and electrons are passed around as you see on the video between different proteins. The whole purpose of this is so that you can pump Hydrogen ions (H+) from inside the membrane to outside the membrane. (remember mitochondrion has 2 membranes? so the H+ stay in between the membranes they don't go outside).
This creates lots of H+ outside compared to inside. And those Mofo H+ outside wanna get inside if you know what I'm sayin. So this creates a way for the cell to make energy using a turbine system called ATP synthase. This ATP synthase is just another protein that comes after this whole chain. but it acts quite literally like a turbine. When the influx of H+ ions try to get in, it spins the "machine" as they flow in and creates energy. This nets approx 38 ATP.
To get a visualization of ATP synthase check the video on the recommended section called "Gradient(ATP synthase).
This is so helpful!! I've been struggling with this concept for so long and was getting disheartened. Your teaching style is a breath of fresh air. Thank you!
THE INTRODUCTION SONG WAS SCARY AS FUCK.
lmaoooo
YES IKR. I WAS KINDA SCARED SINCE IT REMINDED ME OF THE SAW
almost 10 years after learning about the ETC am still amazed by both the discovery and the process itself.
The best description of this process I've seen... By far. Brilliant.
Blatantly ignoring FADH2 okay. This is 2016, many things are now tolerable, this is not one of them. Thanks for the time and effort put into the video though.
+group I agree, there is one more complex on which FADH2 releases its electrons.
+group But your ignoring the fact that this particular video was uploaded
in 2008 not 2016
bro, this video was made 8 years ago..
Jaithen Williams no both are required
Everyone who is saying 8 years ago, we knew FADH2 was involved long before 2008.
Video: "At the start of the electron transport chain, 2 electrons are passed from NADH into the NADH hydrogenase compl-"
Me: "WAIT WAIT! what just happened??"
*Restarts video*
Are you alive?
Wow a seven-year-old comment here
now ur a doctor

Helped me understand Electron Transport Chain and ATP synthase process SO much better than my textbook. Thank you!!!
We used this same exact video when I was in high school and dubbed it for the sake of our requirement. Back then I have no clue what these things are. Now that I'm in med school, this makes so much sense.
wish I'd had animations like this when I was in science class!
Points for inspiring the rest of us.
This was incredibly helpful! Thanks for posting it!
Thank you very much for putting out these fantastically well done animations. While most of the animations on youtube are low quality and not trustworthy, you have set the bar and trust level high. Fantastic.
Are you alive 😅😅😅
This is so useful...i would never have understood this without this animation!
This channel is the best on UA-cam, I love it. Congratulations for the great work accomplished.
THIS MAKES SO MUCH MORE SENSE!!
Definely helped me for my test this friday !!
You forgot about FADH2 in the second complex =(
I hate all the knit picking. Nobody is going to use this as a stand alone study but as a graphical representation of an overall process (that can be very confusing when studied) this is marvelous! Thank you!
a brilliant piece of work that simplifies the whole masterpiece of human combustion and the ABC of life. i love the whole presentation;
I'm watching this during the coronavirus outbreak.
Mee🙋🏻♀️....jus b4 exams
Same
Mee toooo
ok
Same HAHAHA
this is the best video ive ever found on this stuff. great.
Stuff like this makes studying for 1st year med school incredibly fun. Thank you so much!! More of this would certainly make the world a better place :)
I find the video useful, the narration adequately clear, and the process relatively clear. It might be more effective if the names of the electron transport features carried their names and simplified structures as the process takes place, for instance of ubiquinone and the cytochromes. I will definitely use the video to supplement my lecture on respiration. Thanks for all the work that went into it.
decent. my teacher keeps showing us animations from like..the 20's that are ridiculously complicated and confusing. this gives the basics and is from this century. thanks:)
Ubiquinone just became my favourite word :) Thanks for the illustration
Excellent. Sure, it doesn't show everything involved in the chain (lactate dehydrogenase and so on), however it's perfect to understand the general process. Helped me a lot!
i am grateful to you. It will even help me to revise the cycle.
Thank you so much! You made it so much more clear
Yes! Visuals make so much sense to my.. So much better than words.
Awesome post. While I in Cell Bio, I watched your videos. Now, I am back for a review.
Thanks for posting.
FANTASTIC !!! MIND BLOWING !!!!! UNBELIEVABLE!!!!!
THIS IS AMAZING THANK YOU SO MUCH FOR POSTING THIS IT REALLY HELPS!!!
this helped quite a bit with my cell bio studying
Your videos are the BEST!
Thanks, this really helps me out right now!
the intro music sounds like the background music of an unsolved mysteries/horror show
Well, it has idealistically defined my test tomorrow..
1 down. 2 more lessons to go. And it's midnight. Ugh.
welcome to biochemistry, my friend
IKR IT REMINDED ME OF THE SAW
this process cannot be compressed into a simple 4 minute video. but it was a noble attempt
This is so succintly taught, thank you so much!
To be more accurate, the ETC is embedded in the Cristae Membrane which is the INNER membrane of Mithochondria.
Finally a video that explain electron transport chain! I mean, I'm italian and I had to go through english videos to understand something -.- Nice work :D
love these animations, great job. be aware though that you forgot the 2-nd complex, succinate deshydrogenase
this was really helpful in understanding the gradient deal!
It was very clear and useful! Thank you so much!
All your videos are really helpful.. thanks a lot ;) God bless;)
great!fantastic! I would have had a completely wrong picture of this in mind unless i saw it.thanks!
I totally agree.
It's still very good for understanding the process even if it's missing some important steps.
AMAZING! so much easier to understand. than reading it in my book. thanks ! :D
Beautiful. Thank you for this.
Well done indeed. you have saved me a lot of time.
Finally got it!! test tomorrow too! haha
the best animation so far
Amazing job, congrats!!
Thank you! I have a biology test tomorrow and you totally saved me!
Are you a doctor now ?
Amazing video. Because it was published 7 years ago, it doesn't have the most recent discoveries (which may or may not stick in the upcoming 7 years) that Complex 1 (NADH dehydrogenase) does move 4 H+ ions into the intermembrane space.
This still exist
Wow! This is very thorough!!!
Thanks for sharing, It's very useful for my Biochemistry course.
thank you sooooo much , this helped a loooooot
I have a biology exam tomorrow and this helped me a lot
Beautiful.
best video yet
This is the best explanation.👍
This video helped me today to understand this super hard topic so easily
this video helped soooo much, whether or not the exact #s were correct. thanx!
this is by far the best video if seen ,i feel better now:)
Beautiful indeed !!
beautiful. thanks!!
Complex II is missing, but it contributes no protons for ATP synthase to work with so in regards to simplicity i like it. Keeps it simple.
This is awesome! So much better than my teacher.
This is very useful,I mean I was so clueless with regards to this process in Biochemistry.
Amazing explanation
Thanks. I understand electron chains now!
really helped me alot!
thank you very much
These vids are fire!!!
Amazing idea! Keep it up. 👏👏👏👏👏👏👏
THANK YOU SO MUCH!! AMAZING VIDEO!!
Gracias los videos son muy instructivos, y de muy buena calidad.
This is really good!
very helpful since im a visual leaner and coupled with reading my book is super efficient learning!!!!
short and sweet n precise!!!
Can't believe I'm watching this video again 6 years since I last saw it. USMLE step I here I come!!
Thank you so much for uploading this vid; it REALLY helped me figure out the ETC :-)
omg u from the pastt
awesome video simple and to the point
This is the best video for me to understand the Electron Transport Chain. The other videos move too fast over key elements.
thank you so much❤ that helped me a lot
great, but there's a complex II FADH2 deshydrogénase which is missing
Gr8 work . So benificial
It saved my life XO Thankss!!!
crystal clear!! Thanks!!
yes there are dif. H+ pumped, and the complexes change if bacterial, but it's pretty accurate and helps visualize how the electron carriers and couples are positioned.
great animation! it helps a lot! THX~~~~
Finally makes some sense, Finding that with IB bio, the tendency to skim over important details makes things hell to learn, meaning I have to search google just to understand why stuff does what it does, great vid!
The IB brought me here as well. I feel like Respiration is the worst part of the entire Biology Syllabus! :(
Respiration and photosynthesis together, everything else is okayish!
I agree 100%. Are your exams in May 2014, too? :)
yup, what options you doing?:)
helped so much! thank you
awesome. such succinct explanation
"...pumping of one hydrogen ion for each electron..." 1:47
Referring to McGraw-Hill Bio, it's one hydrogen per NADH, meaning one proton per two electrons.
Thanks for your great animation, specially that it is from 15 years ago !
THANK YOU!!
Great work! :)
Several things that would have been useful if they were included:
There is no mention of FADH2. Ubiquinone is also known as Coenzyme Q. I like that the complexes were named, but what about their other names such as Complex I, II (not even mentioned here) III, and IV?
Ya that’s how I learned it in grade 12 now and I’m like where the complex’s at
The electron transport chain is a complex chain that transport electron through the plasma membrane to the ATP synthasis in order to create ATP. The complexes involve in this reaction are NADH dehydrogenes. Cytochrome BC1, Cytochrome oxydaxe and the complexe that makes ATP, two mobiles carrier are also involve: Ubiquonone and cytochrosone C. Other key coponent are NADH, FADH2, O2, H, H2O and ADP and Pi which combine to form ATP. The transport of electron facilited the pumping H out of the cell
Awesome video.
very helpful!! love it!
