Quizplus · Accepted Answer

Organophosphates irreversibly inhibit acetylcholinesterase, the enzyme responsible for breaking down acetylcholine at the neuromuscular junction. This leads to an accumulation of acetylcholine and overstimulation of cholinergic receptors, which can cause symptoms ranging from muscle twitching to respiratory failure.
