What is the importance of acetylcholinesterase in muscle cell contraction?

If the action of acetylcholinesterase wereinhibited, the level of acetylcholine would increase as well as the duration of its action. The effect would cause muscle spasms.
This is because an electrical signal, or nerve impulse, is conducted byacetylcholine across the junction between the nerve and the muscle (the synapse) stimulating the muscle to move. Normally, after the appropriate response is accomplished, acetylcholinesterase is released which breaks down the acetylcholine terminating the stimulation of the muscle. The enzyme acetylcholine accomplishes this by chemically breaking the compound into other compounds and removing them from the nerve junction.
If acetylcholinesterase is unable to breakdown or remove acetylcholine, the muscle can continue to move uncontrollably.
Electrical impulses can fire away continuously unless the number of messages being sent through the synapse is limited by the action of acetylcholinesterase.
Repeated and unchecked firing of electrical signals can cause uncontrolled, rapid twitching of some muscles, paralyzed breathing, convulsions, and in extreme cases, death.

∙ 10y agoThe importance is that acetylcholinerase is something called an enzyme, which digests acetycholine. Acetycholine is something called a neurotransmitter which helps motivate the contraction in the neuromuscular junction.

Which pump is responsible for muscle contraction through depolarization of muscle cell membrane?
Ca2+
What does stretching a myocardial cell cause the cell to do?
Stretching a myocardial cell allows more Ca+2 into the cell and increases the force of contraction (the longer the muscle fiber when it begins to contract, the greater the force of contraction).
What are the three stages of muscle cell contraction?
A Muscle Twitch is a single contraction of skeletal muscle. The three distinct phases are latent, contraction, and relaxation. Latent Phase: Is the interval from the stimulus application until the muscle begins to contract (shorten). Note that there is no traced activity during this phase, but there are some electrical and chemical changes taking place during this phase. Contraction Phase: This phase is when the muscle fibers shorten, the tracings will show during this phase (a) peak(s). Relaxation Phase: This phase is represented by the downward curve in your tracings, this is when the muscle is going back to its original state of relaxation and the muscle will once again lengthen
What is a scaffolding of protein fibers that help a cell keep its shape and assist cell division and cell movement?
The cytoskeleton helps a cell keep its shape. The internal movement of organelles, as well as cell locomotion and muscle fiber contraction couldn't take place without it. The cytoskeleton helps a cell keep its shape. The internal movement of organelles, as well as cell locomotion and muscle fiber contraction couldn't take place without it.
What is sacrolemma?
The sarcolemma is the cell membrane of a muscle fiber. It surrounds and protects the muscle fiber and controls the movement of substances into and out of the cell. The sarcolemma plays a crucial role in muscle contraction and the transmission of nerve impulses to the muscle fiber.
Describe the events of muscle cell contraction?
6 steps in a muscle contraction
Which pump is responsible for muscle contraction through depolarization of muscle cell membrane?
Ca2+
What organelle would be most common in a muscle cell?
Mitochondria - to produce the ATP needed for muscle contraction
What is the muscular structure?
The myofibril is the basic muscle cell, within which is the sarcomere, the basic unit of muscle contraction.
What is the process that takes place in a muscle cell to produce energy for it to work?
Contraction
The final step involved in skeletal muscle contraction is?
The muscle cell relaxes and returns passively to its resting length
What does stretching a myocardial cell cause the cell to do?
Stretching a myocardial cell allows more Ca+2 into the cell and increases the force of contraction (the longer the muscle fiber when it begins to contract, the greater the force of contraction).
Why can the contraction of the muscle tissue cause your arm to bend but the contraction of a single muscle cell would have no effect?
It doesn't have "no effect" ... it's just too feeble to be noticed.
When muscle cell demands energy to perform its work of contraction what happens to ATP?
ATP breaks down when a muscle cell demands energy to perform its work of contraction. ATP, which is a nucleoside triphosphate, stands for adenosine triphosphate.
What are the 4 stages of a muscle cell?
Tonus (relaxation), Excitation (neural stimulation, Clonus (contraction), Tetanus (prolonged contraction), return to Tonus (relaxation) Or Excitation, Excitation-Contraction Coupling, Contraction, Relaxation

What are three characteristics of muscle you can observe under microscope?
Isometric,Isotonic and Twitch-these are the three characeteristics of muscle contraction.
