Sutherland discovered that the signaling molecule epinephrine is responsible for which of the following events?
A) Stimulating glycogen synthesis.
B) Decreasing blood glucose levels.
C) Interacting directly with glycogen phosphorylase.
D) Elevating cytosolic concentrations of cyclic AMP.

Question

Quizplus · Accepted Answer

Sutherland discovered that epinephrine activates adenylyl cyclase, leading to the production of cyclic AMP, which in turn regulates a variety of cellular processes such as glycogenolysis and lipolysis. Therefore, the elevation of cyclic AMP levels by epinephrine is responsible for this event. Choices A, B, and C are not directly linked to epinephrine's action on cyclic AMP.
