And so once we synthesize the ATP, once this rotation takes place, only then will the ATP will actually be able to leave this structure here. So once this rotation takes place this is in an open state. And in the next process, step two, this ATP molecule will be released from this structure and it will travel into the matrix of the mitochondria. While when this goes from the loose state to the 10th state these two reactants are brought close enough for them to begin producing the ATP molecules and this structure. In the open state these reactants can easily leave and enter this structure. But once this conformational change takes place and we enter the loose state these two reactants are now trapped in this conformation.
