Doesn't the bottom portion of ATPsynthase spin as well? My biochem book said that the 3 beta subunits are distinct in that one is always "empty" because its bound to the gamma subunit. Another is awaiting ADP + Pi to come along and be bound, and then the third holds the newly synthesized ATP. When the 3rd unit is turned enough that it has to bind to the gamma subunit, it releases ATP and binds gamma. then the beta unit gets another ADP, turn, makes atp, turn, release atp and bind gamma, etc etc
@JamesBarker85 The bottom portion of the ATP sythase doesn't spin, only the top part does. The top isn't symmetrical though, so it creates a mechanical change in conformation in the bottom, like a square peg twisting in a round opening, the 3 pairs of alpha/beta subunits are squished into different shapes. Each subunit pair are in a state different than the other two, one state is empty, one has ADP+Pi and the last one has ATP. the three pairs of subunits alternate states, depending their state.
I thought that each NADH produced 3 ATPs and each FADH2 produced 2 ATPs on average. If it requires three H+ to produce one ATP, then this would contradict the 38 ATPs produced on average from each glucose.
@rhoadess from viewing the ETC video, each NADH is responsible for pumping 6 hydrogen ions which would account for 2 ATPs, but according to this, it would require 9 hydrogen ions to make the needed 3 ATPs for each NADH. If we assume that 3 ATPs are made for each NADH, and we assume that one full rotation is required to make the 3 ATPs, then for each hydrogen ion, the rotor circumvents 60 degrees.
hmm im still not getting it. Can someone explain to me whats happening when the hydrogen ions enter the atp synthase and how that produces and atp molecule?
@flyers4life123 as it spins, it activates catalytic sites at the stationary (bottom) knob. 3 of these catalytic sites join the phosphate to ATP. So every 3 spins, enough catalytic sites are activated in order to form ATP from phosphate and ADP.
Hej ndsuvirtualcell - thank's for the video. It makes things pretty clear BUT I believe you made a small mistake.
According to your video a flux of H+ is needed so that the ATPsynthase has enough energy to make ATP. It's said in "Biochemistry" from Stryer (2010) that the rotation is only needed to release the ATP. In other words it CAN be synthesised without a proton gradient but NOT released. (see "binding-change mechanism" from Paul Boyer)
@shannunnnnnnn What if some dude on the street came up to you and threatened to kill you w/ his gun unless you taught him how ATP synthases worked? What would you do?
@TTliv87 Theu bind to the F0 unit which causes the F1 unit to rotatate , keeping in mind that fhat or every proton that has been added to the alpha subunit it cases a rotation in the beta subnit this is where an anticolcowise rotation occurs in which the beta subunit changes for 3 conformatios ( open , closed and loose)
Really thank you, thank you. This was a 100% clear animation and summary of what I need to present tomorrow for a school project class. Currently working on the cell and got picked for the Mitochondrien. This surely helped a lot!
This video contains at least one big mistake. The energy of the proton gradient, transformed in mechanic energy isn't the reason for the assembly of ADP with Pi and ATP - this happens automatically by the catalytic envoirment which sinks the activations energy. Rather important is that the motion of the F0-Ring leads to a rotation of the gamma-unit, which has a "bulp" - this bulp rotates and pushes one ATP out of the Betasubunit.
@Snurbify1 Isn't the the rotation mechanical energy? I'm not saying you're wrong I just kind of don't understand the whole 'automatically/spontaneously' by catalytic environment which sinks the activations energy part. could you elaborate?
@kickingtenshi Maybe I'm late with my answer, but I hope you'll still read it! I refered to the fact that the speaker of the video claims that the energy of this process serves the atp condensation - Experiments have shown that also without any proton gradient there are a chemical balance of ATP and ADP in the binding sites of the ATP-Synthetase. The proton gradient supplies the "energy" needed for the rease of ATP from the binding site. This is called the "binding-site change mechanism"
@Snurbify1 therefore the role of the proton gradient is not to form ATP however to relase it from the tight conformation , the complex needs the energy from the protons to rotate the Fo complex allowing the relase of the ATP that had been formed ??
that was very helpful for photosynthesis light-dependent reactions, since ATP synthase is used there also. These are very good videos, and i agree with kashifk9 that you should continue to make them. it will help all the people in honors biology (or in my case 7th grade advanced biology).
the protons are forced by the chemical gradient (Gibbs free energy) to move into the mitochondrion. The only way (for the protons) into the mitochondrion is via the atp synthase.
I wish I watched your vids while taking graduate biochem. I would have had a solid understanding then and probably wouldn't be trying to relearn everything for step 1
Such a huge help. Thank you so much for doing these animations; they make the processes so much clearer than still pictures and pages of explanation or hours of lectures can.

helped out alot.... you can actually see whats going on. Animation is great keep up the good work.. keep them coming, this actually makes biology more understandable, thank you
Really helpful- better than textbooks because you can actually see what's going on rather than just linking long, dry sentences to a small picture in the corner of a page. Thank you!
@wrestle85 You need 1 H+ to come into the matrix with HPO4- (co-transport) to give you Pi to join with ADP so though you only need 3 H+ to turn 120 degrees, your net equation requires 4 H+ per ATP synthesized.
Many thanks for these animations! they have helped me, as a clinician, to better understand basic physiology for my exams and when trying to teach medical students! If only these were around when I was at medical school!
@dw237606 Relax. Know the audience. If this was an all inclusive video of ATP Synthase it'd be hours long. You know alot of Biology but apparently not much practical knowledge.

hey!!!this is incredible,im form argentina and this video help me to my next test...im studing now and tomorrow its the test jajaja...but thanks to this video i think that i will pass the test =P
I have been teaching respiration for decades, and this video is superb for the dynamic way that it shows the "chemo-osmoticly" driven synthesis of ATP. Thank you for the work that went into it, and for posting it for all to benefit from.
Yes they do. The only difference is that plants start with oxidizing water (into oxygen) to create an electrochemical gradient, while animals start with oxidizing NADH. At least I'm almost sure. Need a second opinion.
Yes, it's an important part of oxidative phosphorylation- actually, it's the reason that the electron transport chain even exists. It pumps H+ ions out of the matrix, forming a gradient, and they come back to form ATP. Holy crap, I'm hella nerdy....
Actually photosynthesis and the electron txp chain are basically two similar (almost) system. And in any biological system the energy currency is ATP. Being that both utilizes flavoproteins and cytochromes (heme protein), so it is safe to conclude that both system has almost the same mechanism (atp synthase) for ATP production. The slight difference maybe one that photosynthesis requires photons to excite the photosystems (complex).

haha I know!! I thought I was the only person who thought this! I have to "fast forward" it, because it gives me shivers! and I agree fantastic videos!
Something doesn't ad up. In this video they say that you need 3 Hydrogen ions to produce 1 ATP. It is known that NADH+ knocks 6 hydrogen ions outside the membrane producing 3 ATP when gradient is restored. According to this video it would only produce 2ATP. what is up with that?
(1) NADH+H from complex 1 pumps 4H to the P-side, Complex 3 pumps 4H to the P-side (via Qcycle), and Complex 4 pumps 2H. For a total of 10H on the P-side (intermembrane side) producing approx 3ATP. 1H rotates the F1 unit 120 degrees, requiring 360 degrees to make 1 ATP.
@dpcmonkey Hi, dpcmonkey, I cannot understand when and how 1 complex pumps 4H+ to the P-side, I'm reading Ville right now, but from all sources, including "Cellular Respiration (Electron Transport Chain)" animation I can see that 1 complex pumps 2 H+ [one H+ per one e-].Could you explain or show me reliable source for this information?Also,on animation which I mentioned above,complex 3 pumps 4 H+,but I believe second pair of electrons comes there from FADH from complex 2,not from NADH.
Wow these videos are awesome! So concise. Much better than my former biochemistry teacher! lol

'Electron Transport Animation' by spmarshall69 makes more sense.

Something doesn't ad up. In this video they say that you need 3 Hydrogen ions to produce 1 ATP. It is known that NADH+ knocks 6 hydrogen ions outside the membrane producing 3 ATP when gradient is restored. According to this video it would only produce 2ATP. what is up with that?
castas82 3 years ago
(1) NADH+H from complex 1 pumps 4H to the P-side, Complex 3 pumps 4H to the P-side (via Qcycle), and Complex 4 pumps 2H. For a total of 10H on the P-side (intermembrane side) producing approx 3ATP. 1H rotates the F1 unit 120 degrees, requiring 360 degrees to make 1 ATP.

@dpcmonkey Hi, dpcmonkey, I cannot understand when and how 1 complex pumps 4H+ to the P-side, I'm reading Ville right now, but from all sources, including "Cellular Respiration (Electron Transport Chain)" animation I can see that 1 complex pumps 2 H+ [one H+ per one e-].Could you explain or show me reliable source for this information?Also,on animation which I mentioned above,complex 3 pumps 4 H+,but I believe second pair of electrons comes there from FADH from complex 2,not from NADH.

It's like gasoline, but for animals instead of cars, I guess.
