**Question:**

In healthy individuals, what prevents acetylcholine (ACh) from accumulating in the neuromuscular junction and causing a sustained contraction? Briefly describe what this enzyme does.

**Answer:**

Acetylcholinesterase is the enzyme responsible for breaking down acetylcholine in the synaptic cleft. It hydrolyzes acetylcholine into acetate and choline, thus preventing accumulation. This process stops continuous stimulation of the muscle fibers, allowing muscles to relax after contraction.
