Concept explainers

Muscle Action

A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are the important contractile proteins involved in muscle action. Muscle contraction, in addition to movement, serves several other important functions in the body, including posture, heat generation, and joint stability. Muscle contraction maintains posture, which includes standing and sitting.

Figure 38.37 Which of the following statements about muscle contraction is true? The power stroke occurs when ATP is hydrolyzed to ADP and phosphate. The power stroke occurs when ADP and phosphate dissociate from the myosin head. The power stroke occurs when ADP and phosphate dissociate from the actin active site.

After death, calcium pumps no longer function and the calcium ion concentration of muscle fiber cytoplasm increases. The result is rigor mortis a state or postmortem muscle contraction. Explain why this contraction occurs and why it ends only when myosin heads begin to break down.
Rigor mortis occurs following death because a. tropomyosin remains over the myosin binding sites of actin. b. myosin heads attach to actin and are not released due to lack of ATP. c. the myosin becomes misshapen. d. all of the Ca2+ remains within the sarcoplasmic reticulum.

ATPase is found on troponin.d. Troponin binds to the rodlike portion of myosin.e. Actin molecules have a hingelike portion, which bends and straightensduring contraction.
For relaxation to occur, A. calcium leaves the sarcoplasmic reticulum, and troponin binds calcium and blocks the binding sites on actin. B. calcium enters the myofibril, it detaches from myosin, and the binding sites on myosin become inactive. C. sarcoplasm calcium levels fall, calcium is removed from troponin, and tropomyosin blocks binding sites on actin. D. extracellular calcium levels fall, calcium is pumped into the myofibril, and tropomyosin slides away from actin.
