C)It is actively reabsorbed by the axon terminal.
D)It is passively reabsorbed by the muscle cell.

Question

Quizplus · Accepted Answer

After ACh binds to its receptors, it is quickly broken down by the enzyme acetylcholinesterase (AChE) into acetate and choline. These breakdown products are then reabsorbed by the presynaptic neuron for reuse in the synthesis of new ACh molecules. This allows for precise control of the duration and strength of the synaptic signal.
