You spray an insect with an organophosphate insecticide.How does it kill the insect?
A)It prevents diffusion of acetylcholine at the synapse
B)It destroys the ability of acetylcholinesterase to recycle acetylcholine and allows erratic stimulation and disruption of life activities
C)It kills the insect's neurons and ends its ability to control essential life activities
D)It stops respiration in nerve cells similar to the effect of cyanide

Question

Quizplus · Accepted Answer

Organophosphate insecticides work by inhibiting the activity of acetylcholinesterase, an enzyme that breaks down acetylcholine, a neurotransmitter that plays a key role in nerve impulse transmission. Without acetylcholinesterase activity, acetylcholine builds up in the synapse, leading to overstimulation and disruption of life activities in the insect, ultimately leading to its death.
