Question

Quizplus · Accepted Answer

Cross-bridge cycling, the process by which muscle fibers contract, does not require the muscle fiber to be able to shorten. It involves the interaction between actin and myosin filaments within the muscle cell, which can occur even if the muscle fiber itself is not shortening. The presence of intracellular calcium, ATP, and the ability for ATP hydrolysis are all essential for this process to occur.
