Question

Quizplus · Accepted Answer

Epinephrine degradation in the postsynaptic cell is catalyzed by catechol-O-methyltransferase (COMT). COMT converts epinephrine into metanephrine, which is then further metabolized by monoamine oxidase (MAO). Acetylcholinesterase (Achase) is involved in the degradation of acetylcholine, not epinephrine. Adenylate cyclase plays a role in intracellular signaling, but not in the degradation of epinephrine.
