Where would you find a cholinergeric nicotinic receptor?
all parasympathetic target organs
Where would you not find cholinergeric nicotinic receptor?
all parasympathetic target organs
What statement describes nicotinic acetylcholine ACh receptors as opposed to muscarinic ACh receptors?
Nicotinic receptors are closed until ACh molecules bind to the receptor proteins.
Difference between muscarinic and nicotinic receptors?
1) nicotinic acetyle choline receptors are ligand gated ion channels, where as mucarinic Ach receptors are G-proteins coupled receptors system. 2) nicotine is a agonist/ muscarine( a toxin produced by certain mushrooms) is a agonist. 3) action of nicotine is fast(1-2msec)/action of muscarinic is slow (100-250msec). 4) in case of nicotinic ach receptor, subtypes based on different subunit composition.muscle and neuronal classification/in case of muscarinic receptor at least 5 receptors subtype have been described by molecular cloning. 5) in case of nicotinic receptor agonist effects blocked by tubocuranine/in case of muscarinic receptor agonist effects blocked by atropine. 6) nicotinic receptor found at neuro muscular junction of skeletal muscle, on the post ganglion neurons of the parasympathetic nervous system and on many neurons on the brain(hypothalamus)/muscarinc receptor found at neuromuscular junction of cardiac and smooth muscle as well as on glands and on the post ganglionic neurons of the sympathetic nervous system.
Describe the interaction of acetylcholine and calcium ions in stimulating muscle contraction?
The acetylcholine diffuses across the synapse and binds to and activates nicotinic acetylcholine receptors on the motor end plate of the muscle cell. Activation of the nicotinic receptor opens its intrinsic sodium/potassium channel, causing sodium to rush in and potassium to trickle out.
How does curare cause muscle paralysis?
Curare is a competitive inhibitor of acetylcholine. It fights with acetycholine for postsynaptic receptors.
What are The two types of receptors that bind acetylcholine?
Nicotinic; muscarinic
What is the formula for niacinamide?
Niacinamide is also known as niacinamide and nicotinic amide. It is the amide of nicotinic acid. Its formula is C6H6N2O.
What is ACh receptors?
ACH receptors can be defined as an integral membrane protein that responds to the binding of acetylcholine, a neuoyansmitter. Two example are nicotinic acetyl line receptors and muscarinic acetylcholine receptors. .
What is another name for nicotinic acid?
The answer is "Niacin"
What kind of acid is in coffee?
Nicotinic Aacid
Can nicotinic kill you?
60 mgs will kill you
