Quizplus · Accepted Answer

Cyclic AMP is a well-known second messenger, which is produced by the activation of adenylate cyclase by G-proteins after the binding of extracellular ligands to their membrane receptors. It subsequently triggers intracellular signaling cascades by activating protein kinases and regulating the activity of downstream effectors. Potassium, ATP, and hormones are not classified as second messengers.
