Which of the Following Neurotransmitters is Not Considered a Catecholamine

Question

Which of the following neurotransmitters is not considered a catecholamine?
A) norepinephrine
B) acetylcholine
C) dopamine
D) serotonin

Accepted Answer

Acetylcholine is not a catecholamine. Catecholamines are a class of neurotransmitters that contain a catechol group and an amine group, such as norepinephrine, dopamine, and epinephrine. Serotonin is not a catecholamine either, but it is a monoamine neurotransmitter. Acetylcholine, on the other hand, is a cholinergic neurotransmitter that is not derived from the catecholamine pathway.
