Question

Quizplus · Accepted Answer

Cyclic AMP (cAMP) is an example of a second messenger. Second messengers are molecules that transmit signals from receptors on the cell surface to target molecules or effector proteins within the cell. They are typically small, diffusible molecules that can amplify and modulate signals. cAMP is a small molecule that is generated by the enzymatic activity of an effector protein (in this case, adenylate cyclase) in response to the binding of a ligand (such as a hormone or neurotransmitter) to a G protein-coupled receptor on the cell surface. cAMP then activates downstream target molecules, such as protein kinase A, to mediate a variety of cellular responses.
