The enzyme acetylcholinesterase causes acetylcholine to

A) decompose.

B) synthesize

C) bond to actin.

D) be secreted.

E) form cross-bridges.

A) decompose.

Explanation:

Acetylcholine is a neurotransmitter that acts at the neuromuscular junction and activates the muscles. The neurotransmitter acetylcholine is hydrolyzed by the enzyme acetylcholinesterase into choline and acetate. Due to the activity of acetylcholinesterase, the acetylcholine does not remain for long in the synapses and thus, the synaptic transmission is terminated by the enzyme.
