Which of the following enzymes is important for the metabolism of catecholamines?
A)Tyrosine hydroxylase
B)Acetylcholinesterase
C)Superoxide dismutase
D)Trypsin
E)Adenylyl cyclase

Question

Quizplus · Accepted Answer

Tyrosine hydroxylase is the enzyme responsible for the conversion of tyrosine to L-DOPA, which is the first step in the biosynthesis of catecholamines such as dopamine, epinephrine, and norepinephrine. Acetylcholinesterase is an enzyme that breaks down acetylcholine, a neurotransmitter that is not directly involved in the metabolism of catecholamines. Superoxide dismutase is an enzyme that helps to protect cells against oxidative damage from reactive oxygen species. Trypsin is a digestive enzyme that cleaves peptide bonds in proteins. Adenylyl cyclase is an enzyme that catalyzes the conversion of ATP to cyclic AMP, which is involved in a variety of signaling pathways, but is not specifically related to the metabolism of catecholamines.
