Which statement about a metabotropic neurotransmitter receptor is true?
A) It is a ligand-gated ion channel.
B) It is a voltage-gated ion channel.

E) It causes a very rapid,short-lived change in the membrane.

Question

Quizplus · Accepted Answer

Metabotropic neurotransmitter receptors are G protein-coupled receptors (GPCRs) that activate intracellular signaling pathways to ultimately produce a second messenger. This second messenger, in turn, modulates cellular processes such as ion channels, gene expression, and protein kinases. Therefore, option D is the correct choice as it describes the function of the receptor accurately.
