ATP for muscle contraction can be provided by ______. a. aerobic respiration b. lactate fermentation c. transfer of a phosphate from creatine phosphate d. all of the above
After death, a person no longer makes ATP, so calcium stored in the sarcoplasmic reticulum diffuses down its concentration gradient into the muscle cytoplasm. This result is rigor mortis----an unbreakable state of muscle contraction that stiffens the body for a few days until muscles begin to decay. Explain why this contraction occurs.
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. The power stroke occurs when Ca2+ binds the calcium head.

Within the first few seconds of a 5-minute race, stored ATP isdepleted. How do muscles obtain energy for the rest of the race?a. High-energy phosphates are transferred from glycogen to ADP.b. Creatine phosphate restores the ATP supply at first; then aerobicrespiration generates ATP as long as O2 is available.c. Actin filaments donate the high-energy phosphates that myosinfilaments require.d. Fermentation begins producing new ATP as soon as stored ATP isdepleted.
Fast-twitch muscle fibers have which of the following characteristics?a. fewer number of mitochondriab. rely on fermentation and creatine phosphate pathwaysc. are primarily anaerobicd. provide for a quick release of energye. All of these are correct.
When ATP levels return to normal after intense muscle activity, is creatine predominantly phosphorylated or unphosphorylated? Draw your answer, phosphorylated or unphosphorylated creatine. I know it would be phosphortlated, but what would the correct way to draw it?
The filaments of skeletal muscle are moved by free energy derived from the hydrolysis of ATP. During sustained muscle contraction ATP levels remain fairly constant, while levels of creatine phosphate fall. Explain why this is so. Under what circumstances is an oxygen debt incurred during muscle contraction?
