And once the binding takes place it transforms aspartate 61 of that particular C subunit into a spartic acid. Because a spartic acid is more hydrophobic it wants to move into the core of that inner membrane of the mitochondria and out of this half channel. And so as that rotation takes place it causes the entire serring to actually rotate. So the entire searring then rotates until a C Subian with an aspartic acid enters the half channel that faces the proton poor environment of the matrix of the mitochondria. And once this is found in this position the H plus ion can then move from the hydrophilic environment of this particular hemichannel and, say, the environment that contains a low concentration of those H plus ions. And so we conclude that the movement of the H plus ions through the half channels powers the rotation of that entire Cring.
