Step 1 - Ca2+ released from the sarcoplasmic reticulum , Step 2 - Ca2+ bind to troponin, Step 3 - Troponin changes shape and pulls on tropomyosin, Step 4 - Tropomyosin moves, exposing myosin-binding sites on actin, Step 5 - Myosin head binds to actin, Step 6 - ADP and Pi released from myosin head, Step 7 - Myosin head pulls and slides actin filament past , Step 8 - ATP binds myosin head and releases it from actin, Step 9 - ATP hydrolysis resets the myosin heads in position,
