What are the steps of the sliding filament model? Select all that apply. Sarcomeres are in a relaxed state, in which myosin-binding sites on actin are blocked. When a nervous signal excites the muscle, myosin-binding sites on actin open up and myosin binds to actin. The myosin heads hydrolyze ATP to ADP and P,. The binding of myosin to actin releases phosphate and triggers a power stroke. ATP binds to myosin, and the myosin releases its grip on actin, returning to a relaxed state.
