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.
Acetylcholine is found at the synapses between neurons and muscle cells. It serves to activate the muscle to contract. If acetylcholine receptors sites on the muscle cell are blocked in someway, then the acetylcholine cannot get on the site and the muscles will be incapable of contracting-paralyzed that is.here are two main classes of acetylcholine receptors(acetylcholine receptor is an integral membrane protein that responds to the binding of acetylcholine neurotransmitter), nicotinic acetylcholine receptors and muscarinic acetylcholine receptors.
