What is the role of acetylcholine in a skeletal muscle contraction? Your answer: It binds to receptors and initiates a change in ion permeability that resutls in the contraction of the muscle cell. 3. Describe the process of excitation-contraction coupling in skeletal muscle fibers. Your answer: This is the entire process of the neuromuscular juntion leading to the end-plate potential.
Answers. Best Answer: a) Acetylcholine results in muscle contraction b)Neostigmine acts as a reversible acetylcholinesterase inhibitor, increasing both the level and duration of action of the neurotransmitter acetylcholine. c)d-tubocurarine results in muscle relaxation.It acts as a competitive antagonist of nicotinic neuromuscular acetylcholine receptors, thus inactivating it and preventing ACh to bond and induce contraction.d)Suxamethonium results in muscle relaxation.)d-tubocurarine results in muscle relaxation. It acts as a competitive antagonist of nicotinic neuromuscular acetylcholine receptors, thus inactivating it and preventing ACh to bond and induce contraction.
