Once acetylcholine (ACh) binds to its receptor, it can either stimulate or inhibit the activity of the cell. This activation triggers a cellular response, such as muscle contraction or nerve cell communication. After its action, ACh is rapidly broken down by the enzyme acetylcholinesterase to terminate the signal.
What else can I help you with?
What change does ACh cause in an ACh receptor?
Acetylcholine (ACh) binding to an acetylcholine receptor triggers a conformational change in the receptor protein, leading to the opening of an ion channel within the receptor. This allows specific ions, such as sodium or potassium, to flow across the cell membrane, resulting in changes in membrane potential and ultimately leading to cellular responses.
What is a cholinomimetic agent?
A drug or compound that acts like acetylcholine (ACh). Acetylcholine is a neurotransmitter. In the peripheral nervous system (PNS), acetylcholine activates muscles. In the central nervous system (CNS), acetylcholine tends to cause decreased muscle contractions. These two responses are opposite. ACh Receptor agonists (booster of the effect) are used to treat myasthenia gravis and Alzheimer's disease. ACh receptor antagonists block muscle contractions causing paralysis. The bite of the Black Widow spider does this.
What is the effect of atropine plus acetylcholine on frog heart?
ACh will decrease heart rate/contractile strength, etc. Atropine is a muscarinic ACh receptor (mAChR) antagonist, so blocks the effects of ACh. Adding both together will result in a weak action of ACh that tails off as all the mAChRs become blocked by Atropine.
What destroys ACh?
Acetylcholinesterase (AChE) is an enzyme that breaks down acetylcholine (ACh) into choline and acetate, thus destroying ACh. This process helps in regulating the levels of ACh at the synaptic cleft and terminating its action.
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 change does ACh cause in an ACh receptor?
Acetylcholine (ACh) binding to an acetylcholine receptor triggers a conformational change in the receptor protein, leading to the opening of an ion channel within the receptor. This allows specific ions, such as sodium or potassium, to flow across the cell membrane, resulting in changes in membrane potential and ultimately leading to cellular responses.
Select the option that lists the steps of normal nerve function in the correct order?
ACh is produced at the intercellular level and is stored in vesicles at nerve endings. nerve endings release ACh ACh attavhes to the receptor site at the receiving nerve ACh is broken down by AChE to prevent accumulation

What statement describes nicotinic acetylcholine ACh receptors as opposed to muscarinic ACh receptors?
Nicotinic ACh receptors are ionotropic receptors that mediate fast neurotransmission, while muscarinic ACh receptors are metabotropic receptors that modulate cell signaling through G-proteins. Nicotinic receptors are typically found at neuromuscular junctions and in the central nervous system, whereas muscarinic receptors are more widely distributed in peripheral tissues and the brain.
What happens if your dog ate sheet rock?
what happens is that ur dog probably would get a stomach ach. try taking it to the doctor and give it medicine to help the ach. ur dog will feel more better from thsi treatment! :)
What has the author Friedrich Ach written?

What happens if an ACH payment is returned?
If an ACH payment is returned, it means that the transaction was not successfully processed. This could be due to insufficient funds, incorrect account information, or other reasons. The payment will not be completed, and the sender may incur fees or penalties.
