Which enzyme is responsible for the hydrolysis of the neurotransmitter at the neuromuscular junction to allow muscle relaxation?
Show answer and explanation
Correct answer: Acetylcholinesterase
Acetylcholinesterase breaks down acetylcholine (ACh) in the synaptic cleft. This stops the continuous stimulation of the muscle fiber, allowing the sarcolemma to repolarize and calcium to be pumped back into storage.
