Acetylcholinesterase is an enzyme that breaks down the neurotransmitter acetylcholine into choline and acetate at the synapse. This breakdown is essential to terminate the signal transmission of nerve impulses in the nervous system, allowing for proper muscle relaxation and preventing overstimulation of nerve cells.
What else can I help you with?
What is acetylcholinesterace?
Acetylcholinesterase, also known as AChE, is an enzyme which is critical to the function of animals from ants to elephants. This enzyme's sole responsibility is to break down the neurotransmitter acetylcholine. Acetylcholine sends messages between nerves, signaling muscle contractions. If the neurotransmitter was not broken down after it had served its function, the muscle involved would not be able to relax, and this could create spasms, paralysis, and other problems.
What breaks down acetylcholine?
Acetylcholine is broken down by the enzyme acetylcholinesterase into acetate and choline. This breakdown process is essential for terminating the action of acetylcholine at the synapse, allowing for proper signaling between nerve cells. Excess acetylcholine breakdown can lead to conditions such as myasthenia gravis.
What systems do nerve agents affect?
Nerve agents typically affect the acetylcholine system by irreversibly binding to the enzyme, acetylcholinesterase. This prevents the body from catabolizing acetylcholine, resulting in an accumulation of the neurotransmitter in the synapse and neuromuscular junction.
Mechanism of action of carbamate poisoning?
they inactivate the acetylcholinesterase enzyme which is necessary to break up Ach into acetate and choline,thereby causing increase in synaptic Ach leading to anticholinesterase poisoning...example neostigmine,physostigmine,edrophonium, etc
What is the consequences of the administration of a compound that inhibits acetylcholinesterases?
If the action of acetylcholinesterase is inhibited, acetylcholine is not degraded and would accumulate in the synaptic cleft and act as a constant stimulus to the muscle fiber. The muscle cells will continue to contract resulting in a condition called spastic paralysis.
What is an antiacetylcholinesterase?
It is an enzyme that catalyzes the breakdown of acetylcholine and of some other choline esters that function as neurotransmitters.
Is there a sentence which includes the word acetylcholinesterase if so what is it?
"Acetylcholinesterase" production results in the production of a glucosteroid inhibitor.
How do you pronounce acetylcholinesterase?
Acetylcholinesterase is pronounced uh-SEET-uhl-KOH-lin-ES-ter-ays.
What is the antidote of pyridostigmine?
The antidote for pyridostigmine, which is a reversible acetylcholinesterase inhibitor, is atropine. Atropine works by blocking the effects of excess acetylcholine at muscarinic receptors, alleviating symptoms of cholinergic toxicity. In severe cases, pralidoxime may also be administered to help restore normal function of acetylcholinesterase if there is significant inhibition.
What agent inhibits Acetylcholinesterase?
neostigmine
How is acetylcholine (ACh) removed from the synaptic cleft?
Acetylcholine is degraded by acetylcholinesterase
What is importance of acetylcholinesterase?
Acetylcholinesterase is crucial for neurotransmission, as it breaks down the neurotransmitter acetylcholine in the synaptic cleft, terminating the signal between neurons and muscle cells. This enzyme prevents prolonged stimulation of muscles and ensures proper muscle function and coordination. Additionally, its activity is vital in the central nervous system for regulating synaptic transmission and maintaining cognitive functions. Dysregulation of acetylcholinesterase is associated with various neurological disorders, highlighting its importance in both normal physiology and disease.

What the function for acetylcholinesterase?
Acetylcholinesterase (AChE) is an enzyme that catalyzes the breakdown of the neurotransmitter acetylcholine into acetate and choline in the synaptic cleft. This process is essential for terminating synaptic transmission, allowing neurons to reset and preventing continuous stimulation of the postsynaptic receptor. By regulating acetylcholine levels, AChE plays a crucial role in muscle contraction, learning, and memory. It is also a target for certain drugs and toxins, which can inhibit its function and disrupt normal neural communication.
What is the medical abbreviation meaning Acetylcholinesterase?
ACHe
What is the antidote to organophosphorus poisoning?
The antidote to organophosphorus poisoning is atropine, which is an anticholinergic agent that helps counteract the effects of excessive acetylcholine due to inhibition of the enzyme acetylcholinesterase. Additionally, pralidoxime (2-PAM) can be used to reactivate acetylcholinesterase and restore its function, particularly if administered early. Prompt medical treatment is crucial for effective management of organophosphorus poisoning.
What type of cbrne agent acts by inhibiting a cruicial enzyme called acetylcholinesterase?
Nerve agents are compounds that have the capacity to inactivate the enzyme acetylcholinesterase (AChE)
