And once the ATP is formed, only once the subunit is in the open state can the ATP actually be released from that structure. Now, in the loose state, the bound ATP and Orthophosphate become trapped, but they're not close enough to actually react and form the ATP. So these are the three states. Now, the next question is what determines the actual state of that particular subunit? So let's take a look at the following diagram. So what we see happening in the following diagram is as we go, for instance, from this particular structure to this particular structure, the actual alpha three, beta three hexama ring does not rotate.
