This was something that always baffled and frustrated me in college bio, for which my professor didn't have an answer. "Why does ATP synthase rotate? Wouldn't that cause a loss of energy? What purpose does it serve?". But your explanation cleared that up marvelously after nearly a decade. Thank you.

This seriously show the fierce fight life has to put against entropy.
-
This thing spins at 130 times per second! In some species it even goes at more than 700 RPS!
-
It acts like a turbine! A proton-powered turbine!
-
Amazing how ‘mechanical’ it essentially is. How could it not be.

I always loved the mechanism of ATP synthase, probably one of the first times I truly understood how incredibly complex and exact every mechanism in us has to be. Incredible to think we exist only because so incomprehensibly many small chemical interactions just so happen to be thermodynamically favorable.
-
This is so awe-inspiring. I wish they had animations like this when I was in High School.
-
This is one of the most beautiful videos on the internet; not sure why more people haven't seen it. Fantastic work and thank you for making the world a smarter place!
-
This is deeply complicated and beautiful. My eds mashed

Hi there! Quick note - the bonds that hold the phosphate groups together in ATP are phosphoanhydride bonds, not phosphodiester bonds! Thanks for making this lovely animation, it's very helpful for teaching biology!
-
This tiny engine is 99% efficient by the way
-
Thank you for the animation it is marvelous, it is quite difficult to see only a image in the books, but, now, I can understand how the ATP is synthesized.
-
Ive learned parts of this but have never really seen it all in one place, honestly one of the coolest things ive seen in a while
-
Always loved this thing. The fact that our main energy packets are made by basically motors rotating really fast is amazing
-
Just wonderful! I remember learning the Krebs cycle at med school but this is unbelievable stuff. Amazing work!
-
increasingly interested, so much easier to learn at the level i need when i understand a more in depth version of the process, great video
-
The animation abs simulation is amazing. Please do more simulations like this esp with what’s going on in the organelles during sugar uptakes or lack of oxygen etc
-
I have just discovered this video today, and I am awed and amazed at how fantastic the biochemical machinations that we have in our cells... words cannot describe it completely, but this is one of the coolest things I have see. Thank you for this!
