So this entire brown section to actually dissociate from these two green sections. And so what happens is these active sites which are occupied in the inactive form basically become unoccupied. They become free. And once the active sites are free these catalytic subunits and we have two of them can basically go on and catalyze all these different types of target enzymes via the process of phosphorylation. So once again, cyclic adenosine monophosate binds to allosteric sites found on the regulatory chains. This stimulates the dissociation of the regulatory subunes from the catalytic subunits.
