Question

Quizplus · Accepted Answer

Organophosphates are commonly used as insecticides and can inhibit the activity of acetylcholinesterase, leading to the accumulation of acetylcholine in the synaptic cleft and causing overstimulation of the nervous system.

Other options:
A) Black widow spider venom contains a neurotoxin called alpha-latrotoxin, which causes the release of neurotransmitters, including acetylcholine, leading to muscle spasms and contractions. 
B) Curare is a muscle relaxant that competes with acetylcholine for binding to nicotinic acetylcholine receptors, leading to muscle paralysis. 
C) Clostridium botulinum toxin is a neurotoxin that prevents the release of acetylcholine from nerve endings, leading to muscle paralysis.
