Here are the steps;
step 1. The activated myosin head binds to actin, forming a cross bridge.
Step 2. ADP is released and myosin slides the thin filament toward the center of the sarcomere.
step 3. ATP binds to the myosin head and detaches it from actin
step 4. ATP is hydrolyzed to ADP and P(i) and the energy released re-elevates the myosin head.
