Which of the following is an enzyme that breaks down a neurotransmitter?

  • A. acetylcholine
  • B. serotonin
  • C. dopamine
  • D. acetylcholinesterase
Correct Answer: D

Rationale: Acetylcholinesterase is an enzyme that breaks down the neurotransmitter acetylcholine in the synaptic cleft. This breakdown is essential for terminating the signal and preventing continuous stimulation of the postsynaptic neuron. Acetylcholinesterase ensures that acetylcholine's effects are short-lived and precisely regulated, allowing for controlled neural communication. Dysfunction of this enzyme can lead to neurological disorders.
