The postsynaptic potentials induced by acetylcholine are ended via
A) disruption of the nicotinic postsynaptic receptor.
B) enzymatic degradation via acetylcholinesterase.
C) inhibition of acetylcholine synthesis.
D) facilitation of acetylcholine release.
E) reuptake of acetylcholine.

Question

Quizplus · Accepted Answer

Enzymatic degradation via acetylcholinesterase is the main mechanism for ending the postsynaptic potentials induced by acetylcholine. Acetylcholinesterase breaks down acetylcholine in the synaptic cleft, preventing it from continuously activating the postsynaptic receptors. The other options (A, C, D, E) are not directly involved in terminating the postsynaptic potentials induced by acetylcholine.
