Question

Quizplus · Accepted Answer

The "second messenger" is a molecule that relays signals from receptors on the cell surface to targets inside the cell, and cAMP (cyclic-AMP) is one of the most common second messengers in the body. It is responsible for activating or deactivating a variety of enzymes and proteins in response to external signals. G proteins and receptors are involved in the signaling process, but they are not specifically referred to as "second messengers." Neurotransmitters, on the other hand, are chemical messengers used by neurons to communicate with each other and with other cells, but they are not typically involved in intracellular signaling pathways.
