And remember from our previous discussion the C ring is actually directly connected to that gamma epsilon stalk that runs through that central cavity of that alpha three beta three hexamer. And so what happens is since the ceiling is directly connected to the gamma epsilon central stock it causes that central stock to actually rotate. And when this central stalk actually rotate it stimulates the binding change mechanism that takes place within alpha three beta three hexamer that actually allows the synthesis and the release of those ATP molecules. And so ultimately it's the movement of the protons across the hemi channels across the semichannels of the F Naught region that allows the synthesis of these ATP molecules. Now, I have to mention the following important idea. So the only thing that rotates in ATP synthase is the searing as well as the gamma epsilon structure.
