What would happen to a muscle if there was no acetylcholinesterase present within the neuromuscular junction? the muscle would be unable to contract. the muscle would be unable to relax. neural signals would no longer reach the neuromuscular junction. neural signals would no longer reach the synaptic vesicles.

Neural signals would no longer reach the synaptic vesicles

Explanation:

Acetylcholinesterase is an enzyme present in large quantities in red blood cells, nerve endings and striated muscles. When present at the neuromuscular junction, this enzyme allows neural signals within the muscle to reach more synaptic vesicles, which are the pockets that store neurotransmitters.

When this enzyme is released in the synaptic vesicles in constant amounts, it allows the depolarization of a nerve termination. As a result of this, an influx of calcium occurs that allows the fusion of the membrane of the vesicle with the plasma membrane of a nerve-ending cell.
