Question 8 During a muscle contraction, myosin molecules on the thick filament split ATP into ADP and Pi. This releases energy and allows myosin to form cross-bridges with actin on the thin filament. When ADP and Pi are released, myosin flexes and tugs on the thin filament. This causes the thin filament to slide a short distance towards the center of the sarcomere. This is called the stroke.
