Acetylcholine in the synaptic cleft is broken down by the enzyme acetylcholinesterase. This enzyme rapidly hydrolyzes acetylcholine into choline and acetate, terminating the signal transmission at the synapse.

How are neurotransmitters broken down in the synaptic cleft?
Neurotransmitters are broken down in the synaptic cleft by enzymes called monoamine oxidase and catechol-O-methyltransferase, depending on the type of neurotransmitter. These enzymes break down neurotransmitters into metabolites that are either taken back up by the pre-synaptic neuron for recycling or diffused away.
A chemical that destroys acetylcholine a brief period after its release by the axonal endings is?
Acetylcholinesterase is the enzyme that breaks down acetylcholine at the synaptic cleft, terminating its action. This allows for the proper regulation of acetylcholine levels in the synaptic space and prevents continuous stimulation of the postsynaptic neuron.
Acetylcholinesterase is an enzyme located on or immediately outside the?
Acetylcholinesterase is an enzyme located on or immediately outside the synaptic cleft. It is responsible for breaking down the neurotransmitter acetylcholine into choline and acetate, allowing for the termination of nerve signal transmission.
What occurs when neurons are released into the synaptic cleft?
Neurotransmitters are released into the synaptic cleft where they bind to receptors on the postsynaptic neuron. This triggers a response in the postsynaptic neuron, either excitatory or inhibitory, which can lead to the generation of an action potential. The neurotransmitters are then either broken down or taken back up by the presynaptic neuron for recycling.
What happens to the neurotransmitter once it is released?
Once released, the neurotransmitter travels across the synaptic gap and binds to receptors on the membrane of the target cell. This binding induces a response in the target cell, such as an action potential or a change in cellular activity. The neurotransmitter is then either broken down by enzymes, taken back up into the presynaptic neuron for recycling, or diffuses away.
How is acetylcholine (ACh) removed from the synaptic cleft?
Acetylcholine is degraded by acetylcholinesterase
What neurotransmitter does not go through the re-uptake process?
Acetylcholine is a neurotransmitter that does not go through the reuptake process. Instead, it is broken down by an enzyme called acetylcholinesterase in the synaptic cleft.
How are neurotransmitters broken down in the synaptic cleft?
Neurotransmitters are broken down in the synaptic cleft by enzymes called monoamine oxidase and catechol-O-methyltransferase, depending on the type of neurotransmitter. These enzymes break down neurotransmitters into metabolites that are either taken back up by the pre-synaptic neuron for recycling or diffused away.
Where is acetycholine broken down into acetate and choline?
Acetycholine is broken down into acetate and choline in the synaptic cleft.
What enzyme has to be present for acetylcholine to be broken down so that the muscle fiber can relax?
Acetylcholinesterase is the enzyme responsible for breaking down acetylcholine in the synaptic cleft, allowing the muscle fiber to relax. This enzyme catalyzes the hydrolysis of acetylcholine into acetate and choline, preventing continuous stimulation of the muscle.
What does acetylcholinerase do?
Also known as AChE, Acetylcholinesterase is an enzyme that breaks down the neurotransmitter acetylcholine, resulting in choline and an acetate group. This occurs at the synaptic cleft. Too much acetylcholine can lead to paralysis
What decomposes acetylcholine into acetate and choline?
Acetylcholinesterase is the enzyme responsible for breaking down acetylcholine into acetate and choline in the synaptic cleft. This breakdown process is essential for signal termination in cholinergic neurotransmission.
A chemical that destroys acetylcholine a brief period after its release by the axonal endings is?
Acetylcholinesterase is the enzyme that breaks down acetylcholine at the synaptic cleft, terminating its action. This allows for the proper regulation of acetylcholine levels in the synaptic space and prevents continuous stimulation of the postsynaptic neuron.
In the synaptic cleft of a neuromuscular junction what enzyme is always present?
Acetylcholinesterase is always present in the synaptic cleft of a neuromuscular junction. It is responsible for breaking down the neurotransmitter acetylcholine, allowing for the termination of the signal transmission between the neuron and the muscle cell.
What is the Process by which ACh gets across cleft?
Acetylcholine (ACh) is released from the presynaptic neuron into the synaptic cleft. It then binds to ACh receptors on the postsynaptic neuron, causing ion channels to open and allowing for the transmission of the nerve impulse. Any remaining ACh is broken down by the enzyme acetylcholinesterase, ensuring that the signal is quickly terminated.
What destroy acetylcholine?
Acetylcholinesterase is an enzyme that breaks down acetylcholine into choline and acetate. Certain toxins, such as organophosphates and nerve agents, can also inhibit acetylcholinesterase activity, leading to an accumulation of acetylcholine in the synaptic cleft.
What is the stimulus for Acetylcholine release?
The stimulus for acetylcholine release is the action potential traveling down the axon of the presynaptic neuron. This depolarization causes calcium channels to open, allowing calcium ions to enter the axon terminal and trigger the release of acetylcholine into the synaptic cleft.
