By inhibiting acetylcholinesterase, what effect occurs?

Explanation:
Acetylcholine signaling lasts longer when acetylcholinesterase is inhibited because the enzyme’s job is to rapidly break down acetylcholine in the synaptic cleft. If the enzyme is blocked, acetylcholine isn’t degraded as quickly, so it remains around longer and keeps stimulating its receptors (both muscarinic and nicotinic). That extended presence translates to prolonged signaling. The other ideas don’t fit: decreasing signaling would require less acetylcholine or receptor blockage; blocking receptors would stop signaling; and dopamine degradation isn’t directly affected by acetylcholinesterase inhibitors.
