Question 5

During skeletal muscle contraction, which of the following events directly leads to the shortening of the muscle fiber?

Accepted Answer

B. Formation of cross-bridges between actin and myosin filaments. — The direct event that causes the shortening of a muscle fiber is the formation of cross-bridges between the myosin heads and actin filaments, followed by the 'power stroke' where myosin pulls the actin filaments towards the center of the sarcomere. Calcium release initiates this process, and ATP hydrolysis provides the energy for the power stroke and detachment, but cross-bridge formation and subsequent pulling are the direct cause of muscle shortening.

Answer

A. Release of calcium ions from the sarcoplasmic reticulum.

Answer

C. Hydrolysis of ATP by myosin heads.

Answer
