What else can I help you with?
Acetylcholine in the synaptic cleft is broken down by?
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.
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 do Muscarinic receptors bind?
Muscarinic receptors bind acetylcholine, which is a neurotransmitter in the parasympathetic nervous system. Activation of muscarinic receptors leads to various physiological responses in organs and tissues innervated by parasympathetic neurons.
What enzyme is inhibited by a nerve agent?
Acetylcholinesterase is the enzyme inhibited by nerve agents. This enzyme is responsible for breaking down the neurotransmitter acetylcholine, and when inhibited, leads to an accumulation of acetylcholine at nerve synapses causing overstimulation of muscles and nerves.
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.
What prevents acetylcholine from accumulating in the neuromuscular junction?
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.
How is acetylcholine (ACh) removed from the synaptic cleft?
Acetylcholine is degraded by acetylcholinesterase
What kind of enzyme breaks down acetylcholine?
Acetylcholinesterase
Acetylcholine in the synaptic cleft is broken down by?
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.
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 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 responsible for degrading acetylcholine so that it does not remain in the synapse?
acetylcholinesterase
Cleans up chemicals released by nerve cells?
AchE Acetylcholinesterase. It cleans up Ach Acetylcholine
How do nerve agents produce in the body?
they inhibit the enzyme Acetylcholinesterase (AChE) allowing Acetylcholine (ACh) to accumulate.
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.
Help to counteract nerve agent poisoning?
Nerve agents are acetylcholinesterase inhibitors. Acetylcholinesterase is an enzyme that breaks down acetylcholine at nerve synapses. The antidote to counteract the nerve agent is an anticholinergic drug, such as atropine.
How is the neurotransmitter acetylcholine inactivated at the parasympathetic terminal receptor site?
Acetylcholine is primarily inactivated at the parasympathetic terminal receptor site by the enzyme acetylcholinesterase. Acetylcholinesterase breaks down acetylcholine into choline and acetate, which are then taken back up by the presynaptic terminal for further use in neurotransmitter synthesis. This inactivation process allows for the rapid termination of acetylcholine signaling and helps maintain proper neurotransmitter balance in the synapse.
