Answer
C. If acetylchlolinesterase is poisoned then it takes a longer time for released acetylcholine neurotransmitter to be cleared from the synaptic cleft. This gives the neurotransmitter a longer time to act. The result is that the level and duration of neurotransmitter action is increased.
Work Step by Step
Poisoning of acetylcholinesterase increases the time required for acetylcholine ti be cleared from a synaptic cletf. This gives the neurotransmitter a longer time to act with consequent prolonged depolarization.This blocks neurotransmission.
