When the Neurotransmitter Acetylcholine Is Applied to Skeletal Muscle Cells

When the neurotransmitter acetylcholine is applied to skeletal muscle cells, it binds the acetylcholine receptor and causes the muscle cells to contract.Succinylcholine, which is a chemical analog of acetylcholine, binds to the acetylcholine receptor on skeletal muscle cells but causes the muscle cells to relax; it is therefore often used by surgeons as a muscle relaxant.Propose a model for why succinylcholine causes muscle relaxation.What might be the mechanism to explain the different activities of acetylcholine and succinylcholine on the acetylcholine receptor?
