Question

One of the MOST common regulatory second messengers in cells is: A) FAD. B) NAD⁺. C) coenzyme A. D) ATP. E) cAMP.

Accepted Answer

cAMP, or cyclic adenosine monophosphate, is a very common regulatory second messenger in cells. It is formed from ATP through the action of an enzyme called adenylate cyclase and is involved in many signaling pathways, including those involved in regulating metabolism, gene expression, and cell growth and differentiation.
