5. Number the events of skeletal muscle contraction in correct order: ________ calcium ions bind to troponin on the thin filament. ________ tropomyosin shifts, exposing the myosin binding site. ________A power stroke occurs as the myosin head pulls the thin filament towards the m-line . ________ADP and phosphate are released from the myosin head. ________the myosin head binds to the myosin binding site. ________ATP is hydrolyzed and the myosin head is cocked into its resting position. ________ the sarcoplasmic reticulum...

8 Number the following events of skeletal muscle contraction in the proper order, with number 1 for the first event and number 6 for the last event. A power stroke occurs as myosin moves into its relaxed position and pulls the thin filament toward the M line. Calcium ions bind to troponin, which pulls tropomyosin away from actin. ATP breaks the actin-myosin attachment, after which ATP is hydrolyzed and myosin is recocked. The myosin head binds to an actin subunit....

1. True -False. If a statement is True, place a T to the left of it. If a statement is False, place an F to the left of it. Thin filaments in smooth muscles attach to Z discs. The majority of ventricular filling occurs during the period of atrial contraction known as the period of rapid filling. Closure of the atrioventricular valves occurs at the end of diastole/beginning of systole. Tetanus in skeletal muscles is the result of increasing the...
