Muscle contraction is caused by

Question

Quizplus · Accepted Answer

Muscle contraction is caused by the sliding of myosin filaments along actin filaments. This is made possible by the interaction between actin and myosin, with the energy for this biological movement provided by ATP. Movement of bones that anchor the muscles is a result of the muscle contraction, rather than the cause of it. Sarcomeres moving along other sarcomeres and contraction of actin and myosin filaments are not accurate explanations of the process of muscle contraction.
