Which of the following statements about nicotinic and muscarinic receptors is true?

Question

Quizplus · Accepted Answer

Nicotinic receptors are ligand-gated ion channels that open in response to binding of acetylcholine, causing sodium influx and depolarization. They are therefore ionotropic receptors. Muscarinic receptors, on the other hand, are G protein-coupled receptors that activate intracellular signaling pathways in response to acetylcholine binding, and are therefore metabotropic receptors.
