So on the other side, we have this g protein that contains a GDP bound to it. When the GDP is bound to it, it is inactive. But upon the binding of glucagon, the GDP is expelled and a GTP enters this pocket. And once the GTP is bound, it activates the g protein, causes it to actually dissociate from this orange glucagon receptor. And once this g protein dissociates, it moves on onto adenylate cyclist. And what it does is it stimulates adenylit cyclase and enzyme to basically begin the catalyzation the transformation of ATP molecules into cyclic amp molecules.
