in a neuromuscular synapse, which of the following breaks down the neurotransmitter released from the axon?
the enzyme acetylcholinesterase
the motor end plate
the arrival of additional impulses at the axon terminal
the creation of additional synaptic vesicles

The correct answer for this question would be the first option. In a neuromuscular synapse, it is the enzyme acetylcholinesterase, which is located at the motor end plate, that breaks down the neurotransmitter released from the axon. This is responsible for stimulating terminating the stimulation of the skeletal muscle cell to make it contract. Hope this answer helps. 

The answer is  a.first and third quarters
