Put the following steps in E-C coupling in order. Start with ATP binds to myosin.
- myosin releases ADP
- Myosin releases inorganic phosphate and the myosin swivels, allowing the actin filament to move toward the M line
- ATP binds to myosin
- myosin affinity for actin decreases, and myosin releases actin
- Myosin breaks ATP into ADP and inorganic phosphate
- The energy from ATP hydrolysis causes the myosin head to rotate to a cocked position and bind weakly to actin
