Question

Quizplus · Accepted Answer

The predominant second messenger involved in regulating glucose metabolism is cAMP, which is involved in the signaling pathways of both insulin and glucagon. Adenyl cyclase is the enzyme responsible for the production of cAMP. Therefore, choices C and E are also somewhat correct, but D is the best choice as a specific and direct answer to the question. Insulin itself is not a second messenger but rather a hormone that triggers the activation of second messenger pathways, including cAMP.
