Question

Quizplus · Accepted Answer

G-proteins are known to activate effector enzymes, such as adenylyl cyclase, phospholipase C, and ion channels. The binding of an extracellular ligand to a G-protein coupled receptor triggers a conformational change that leads to the activation of the associated G-protein, which in turn activates the effector enzyme.
