Which of the following statements about acetylcholine is correct?
A)Acetylcholine binds to cholinergic receptors
B)Acetylcholine binds to nicotinic and muscarinic receptors
C)Acetylcholine synthesis is catalyzed by acetylcholinesterase
D)Both acetylcholine binds to cholinergic receptors and acetylcholine binds to nicotinic and muscarinic receptors are correct
E)Both acetylcholine binds to cholinergic receptors and acetylcholine synthesis is catalyzed by acetylcholinesterase are correct

Question

Quizplus · Accepted Answer

Acetylcholine binds to both cholinergic receptors (which include both nicotinic and muscarinic receptors) and therefore both options A and B are correct. Acetylcholine synthesis is not catalyzed by acetylcholinesterase, but rather acetylcholinesterase is responsible for breaking down acetylcholine after it has been released into the synapse. Therefore, option C is incorrect.
