Which step in the actomyosin cycle involves ATP hydrolysis?

Step 5: Myosin power stroke pulls actin towards the M disc.

Step 1: Myosin binds tightly to actin without ATP.

Step 3: ATP hydrolysis causes the myosin head to change to a high-energy state.

Step 2: ATP binds to myosin, disrupting actin-myosin interaction.
