b. Gardiac Smooth C. 2. Put the following steps of muscle contraction in order: a. b. C. d. The sarcomere of the muscle fiber shortens, contracting the muscle. The active sites on the actin filament are blocked by troponin & tropomyosin. The myosin heads create a cross-bridge with the actin filament & cause a power stroke. Calcium ions bind to the troponin & tropomyosin & change the structure so that the active sites are free. e. The Calcium ions are pumped back out of the muscle fiber and the troponin & tropomyosin block the active sites again. f. The myosin heads store energy from ATP and enter the "cocked" position like a spring. Another ATP provides energy to the myosin head and it releases, causing a return stroke. 3. Label the following structures: g.
