Verified
The function of acetylcholinesterase is to
A) open voltage-gated Na+ channels.
B) break down acetylcholine in the synapse.
C) produce an IPSP on the postsynaptic membrane.
D) metabolize norepinephrine.
Acetylcholinesterase
Enzyme found in the synaptic cleft that causes the breakdown of acetylcholine to acetic acid and choline, thus limiting the stimulatory effect of acetylcholine.
Acetylcholine
A neurotransmitter involved in many functions including muscle contraction and the transmission of nerve impulses in the central and peripheral nervous system.
Synapse
The junction between two neurons, where electrical or chemical signals are transmitted from one neuron to another.

Final Answer :
B
Explanation :
Acetylcholinesterase is an enzyme that breaks down acetylcholine in the synaptic cleft, ensuring that the neurotransmitter does not continue to act on the postsynaptic neuron, thus terminating the signal.
