Question

Quizplus · Accepted Answer

Organophosphate insecticides work by inhibiting the activity of acetylcholinesterase, the enzyme responsible for the breakdown of the neurotransmitter acetylcholine. By doing so, the insect's nervous system is flooded with acetylcholine, leading to erratic stimulation and disruption of life activities. This ultimately results in the insect's death.
