When a hormone binds to a membrane-bound receptor and activates G proteins, A)ion channels could be opened. B)IP₃ may be activated. C)cyclic AMP production may be increased. D)DAG may be activated. E)All of the choices may occur from activated G proteins.

Question

Quizplus · Accepted Answer

Activated G proteins can lead to a variety of downstream effects, including opening of ion channels, activation of intracellular enzymes such as adenylate cyclase (resulting in increased production of cyclic AMP), and activation of second messengers such as DAG. Therefore, all of the choices may occur from activated G proteins.
