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.
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 nicotin â¦ ic receptor opens its intrinsic sodium/potassium channel, causing sodium to rush in and potassium to trickle out. 3 people found this useful.
