Question
Recall that acetylcholine is a ligand that binds to the acetylcholine receptor, a ligand gated ion channel. The channel opens when acetylcholine is bound and allows Na+ to enter the cell. Succinylcholine is an acetylcholine analog and is used as a muscle relaxant during surgery. Succinylcholine acts by binding the acetylcholine receptor, activating the receptor, and maintaining the channel in an open state. This results in the depolarization of the muscle cell which leads to muscle relaxation. Which of the following best describes succinylcholine? Succinylcholine is an antagonist Succinylcholine is an agonist Succinylcholine is the natural biological ligand for the acetylcholine receptor Succinylcholine is an ionophore Succinylcholine is an enzymeExplanation / Answer
Answer:B-Succinylcholine is an agonist .
Succinycholine is a depolarizing skeletal muscle relaxant .As does acetylcholine, it combines with cholinergic receptors of the motor end plate to produce depolarization.Succinylcholine is a nicotinic agonist.
