Practice Worksheet B
Sequence of muscle contraction
Number the following statements in their proper sequence to describe the contraction mechanism in a skeletal muscle cell.
_____ A. Acetylcholine is released into the neuromuscular junction by the axonal terminal.
_____ B. The action potential, carried deep into the cell, causes the sarcoplasmic reticulum to release calcium ions.
____ C. The muscle cell relaxes and lengthens.
_____ D. Acetylcholine diffuses across the neuromuscular junction and binds to receptors on the sarcolemma.
____ E. The calcium ion concentration at the myofilaments increases; the myofilaments slide past one another, and the cell shortens.
_____ F. Depolarization occurs, and the action potential is generated.
_____ G. As calcium is actively reabsorbed into the sarcoplasmic reticulum, its concentration at the myofilaments decreases.
Focus on the interaction of ATP with the kinase first. Would you say ATP binds on the surface of the kinase or in a cleft?
