Quizplus · Accepted Answer

In the sliding filament model, bridges form between the actin and myosin during contraction, which requires the release of calcium from the endoplasmic reticulum. The formation of these bridges requires energy, which comes from the breakdown of ATP. Therefore, all of the above options must occur in order for a sarcomere to contract.
