Nerve
It is an enzyme that catalyzes the breakdown of acetylcholine and of some other choline esters that function as neurotransmitters.
Nerve agents are compounds that have the capacity to inactivate the enzyme acetylcholinesterase (AChE)
The nerve agents (commonly called nerve gases, but several are more like motor oil than gas).
Acetylcholinesterase
acetylcholinesterase
postsynaptic membrane
The presence of an enzyme called acetylcholinesterasethat degrades acetylcholine is what prevents an accumulation of the neurotransmitter and sustained muscle contraction. Acetylcholinesterase is an enzyme that can be found within the neuromuscular junction. Thus, when a nerve impulse causes the release of acetylcholine at the neuromuscular junction, there is a critical time in which the neurotransmitter can bind to receptors on the muscle before it is degraded.
Acetylcholine is degraded by acetylcholinesterase
