It is now known to be a neurotransmitter at all autonomic ganglia, at many autonomically innervated organs, at the neuromuscular junction, and at many The rapid nature of the synaptic transmission mediated by the nicotinic receptor is consistent with its role at the NMJ and in the ganglion of the ANS.Acetylcholinesterase, also known as AChE or acetylhydrolase, is a serine protease that hydrolyzes the neurotransmitter acetylcholine. AChE is found at mainly neuromuscular junctions and cholinergic brain synapses, where its activity serves to terminate synaptic transmission.Any substance that inhibits acetylcholinesterase (AchE), an enzyme that breaks down acetylcholine (Ach) in the synaptic cleft. Inhibition of acetylcholinesterase results in an increase in the level and duration of action of acetylcholine.What is Cholinesterase enzyme? Neurophysiology A hydrolase that metabolizes acetylcholine to acetyl and choline in the synaptic cleft, restoring it to a ground state, in preparation for the next nerve impule; acetylcholinesterase is found in the CNS, RBCs, motor endplates....is its role? an enzyme known as acetylcholinesterase is present in the synaptic cleft. what is its role? to pump ca2+ back out of the axon terminal to facilitate the entrance of acetylcholine into the muscle cell to break down acetylcholine to facilitated transport of acetylcholine across the cleft.
What is the role of acetylcholinesterase at a synapse?
In addition to terminating neurotransmission by hydrolyzing acetylcholine, synaptic acetylcholinesterase (AChES) has been found to have a pro-apoptotic role. It also cleaves chromosomal DNA both in pre-fixed and in apoptotic cells. In the presence of a pan-caspase inhibitor...In General, Is This Enzym Free To Diffuse Away From The Synapse? For example, is it found on the presynaptic membrane or on the postynaptic membrane or as a soluble enzyme in the synaptic cleft or...?Acetylcholinesterase is a component of the postsynaptic membrane of cholinergic synapses of the nervous system in both vertebrates and invertebrates. The resulting increase in concentration of Ca++ ions in the intracellular fluid facilitates exocytosis of the neurotransmitter into the synaptic cleft.Inhibition of acetylcholinesterase preserves the acetylcholine in the synaptic cleft, making it more likely to reach the few remaining receptors. The carbamates are also used in the treatment of glaucoma and in reversing the action of neuromuscular blocking agents after anaesthesia.

Answer: Acetylcholinesterase is an enzyme that breaks down the neurotransmitter acetylcholine. Acetylcholinesterase inhibitors can also be used therapeutically in a few cases. For one, treatment of myasthenia gravis, a neurological disease that results from destruction of nicotinic acetylcholine...At cholinergic synapses, acetylcholinesterase is present in the synaptic cleft. This enzyme cleaves the neurotransmitter into acetate and choline, neither of which is active. Serotonin and epinephrine, on the other hand, are taken up into the presynaptic terminal and recycled.The synaptic cleft, presynaptic terminal, and receiving dendrite of the next cell together form a junction known as the synapse. …by a gap called the synaptic cleft, across which neurotransmitters diffuse when released from the vesicles. In nerve-muscle junctions the synaptic cleft contains a structure...Both these enzymes present multiple molecular variants which possess identical catalytic activity but differ in their molecular structure and interactions. Anglister L, McMahan UJ (1983) Acetylcholinesterase in the synaptic basal lamina of damaged muscle fibers (Abstr).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.
b. It breaks down acetylcholine.
Acetylcholinesterase, additionally known as AChE or acetylhydrolase, is a serine protease that hydrolyzes the neurotransmitter acetylcholine. AChE is discovered at basically neuromuscular junctions and cholinergic mind synapses, the place its task serves to terminate synaptic transmission. It belongs to carboxylesterase family of enzymes.
