What is acetylcholine?

Answer 1

Acetylcholine is a neurotransmitter that is released in the synaptic cleft and goes over the sarcolemma down the tubule and promotes the release of calcium from the sarcoreticulum which then binds to proteins on actin which exposes binding spots for myosin to attach to and powerstroke causing muscle contraction.
movement, learning, memory, and sleep.

Answer 2

Wow, that could take a long time to explain. In summary it carries signals from one nerve cell to another through a junction called a synapse.

To go further would take lots of explanation.

Answer 3

the peripheral nervous system and central system requires neurotransmitter for its fucntionalities that is called acetylcholine. it is synthesized from two different molecules known as choline and acetyl. it is pivotal for the working of the brain and involved in healthy development of memory, enhance learning power, sustaining information for greater length of time. it helps the brain and enables it to choose what subjects to focus on.

Answer 4

In summary, excite the muscle cell.

In a little more detailed summary, acetylcholine is a neurotransmitter that reversibly binds to and stimulates the muscarinic acetylcholine receptors on the post-synaptic region of the sarcolemma of the skeletal muscle, called the motor end plate. The result of this binding of acetylcholine to the acetylcholine receptor is opening of sodium channels and influx of sodium cations into the muscle cell, causing the resting potential of that muscle cell to begin to depolarize. This depolarization at the end plate of the sarcolemma of the muscle cell causes an end plate potential. This end plate potential results in further depolarization of the sarcolemma membrane, resulting in formation of an action potential that propagates along the muscle fiber. This action potential causes the sarcoplasmic reticulum to release calcium cations inside the cell. The increased intracellular calcium concentration activates actin and myosin activity within the sarcomere, causing contraction of a muscle.

Basically, acetylcholine is the neurotransmitter or chemical messenger that the nerve cell uses to communicate with the muscle cell. The result of this communication is electrical excitation of the muscle cell, what we call an action potential. The action potential of the muscle cell activates that muscle and causes the muscle cell to contract or shorten. This is how our muscles are activated to do work.

Answer 5

Acethylcholine is a neurotransmitter in the nervous system.

The IUPAC name is 2-acetoxy-N,N,N-trimethylethanaminium and the chemical formula is C7NH16O+.
