What else can I help you with?
A poisonous gas destroys the enzyme that breaks down acetylcholine. What effect do you think this gas has on the body?
If the enzyme that breaks down acetylcholine is destroyed, acetylcholine levels in the body will increase. This can lead to overstimulation of muscles and nerves, causing symptoms like muscle twitching, paralysis, respiratory failure, and even death.
What do actylcholine and cholinesterase do?
Acetylcholine is a neurotransmitter responsible for transmitting signals in the nervous system. Cholinesterase is an enzyme that breaks down acetylcholine into choline and acetate, terminating the neurotransmitter's signal transmission.
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 is anticholinesterase?
An anticholinesterase is an agent which inhibits the activity of cholinesterase.
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.
What kind of enzyme breaks down acetylcholine?
Acetylcholinesterase
A poisonous gas destroys the enzyme that breaks down acetylcholine. What effect do you think this gas has on the body?
If the enzyme that breaks down acetylcholine is destroyed, acetylcholine levels in the body will increase. This can lead to overstimulation of muscles and nerves, causing symptoms like muscle twitching, paralysis, respiratory failure, and even death.
What do actylcholine and cholinesterase do?
Acetylcholine is a neurotransmitter responsible for transmitting signals in the nervous system. Cholinesterase is an enzyme that breaks down acetylcholine into choline and acetate, terminating the neurotransmitter's signal transmission.
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 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
Cholinesterase causes acetylcholine to do what?
Cholinesterase breaks down acetylcholine into choline and acetic acid. This process helps to quickly terminate the signal transmission at cholinergic synapses, preventing overstimulation and allowing the synapse to reset for the next signal.
What is cholinesterase?
It's an enzyme that breaks down the neurotransmitter acetylcholine. Basically, neurotransmitters are necessary for nerves to transmit impulses and messages throughout the body. Acetylcholine is used specifically to transmit sensory messages. Sometimes, the body produces so much acetylcholine that it becomes an annoyance. In these cases, cholinesterase is responsible for balancing out the production of acetylcholine by destroying it.
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 prevents ACh from accummulating in the neromuscular junction?
Acetylcholinesterase is an enzyme that breaks down acetylcholine into choline and acetate at the neuromuscular junction. This prevents acetylcholine from accumulating and allows for efficient signaling between the nerve cell and the muscle cell.
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.
When acetylcholine diffuses across syaptic cleft?
Like any other neurotransmitter, acetylcholine will attach itself to active sites on the dendrite, thus triggering the opening of sodium gates of the next neuron. Once that's done, the acetylcholine either breaks down or is absorbed back into the cell it originated from.
What do you think the effect of breaking down acetylcholine is on muscle contraction?
Breaking down acetylcholine can lead to muscle relaxation because acetylcholine is a neurotransmitter that stimulates muscle contraction. When acetylcholine is broken down, the signal for muscle contraction is reduced, resulting in muscle relaxation.
