Question: Put these events in the correct chronological sequence: 1. End-plate potentials trigger action potentials. 2. Transverse tubules convey action potentials into the interior of the cell. 3. Acetylcholine binds to receptors on the motor end plate. 4. Binding sites on actin are uncovered , allowing myosin to bind and carry out power strokes. 5. Calcium ions are released from the sarcoplasmic reticulum. 6. Chemically regulated ion channels open, causing depolarization. 7. Calcium ions bind to troponin, pulling tropomyosin away from myosin-binding sites on actin.
