How does sarin inhibit acetylcholinesterase
WebSarin is a nerve agent, which means it interferes with the normal signaling between nerve cells. It acts in much the same way as organophosphate insecticides, block nerve endings from allowing muscles to stop contracting. Death may occur when the muscles controlling breathing become ineffective, causing asphyxiation. WebOct 1, 2004 · By their inhibitory effect on the enzyme acetylcholinesterase, these drugs increase the amount of acetylcholine at the neuromuscular junction, thus overcoming the effects of any residual neuromuscular blocking agent.
