Why do you think a person is able to perform anaerobic exercise (such as lifting and holding a heavy weight) only briefly but can sustain aerobic exercise (such as walking or swimming) for long periods? (Hint: Muscles have limited energy stores.)
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.
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
Cheetahs and human sprinters tend to have a high proportion of ________fibers in their leg muscles. a. white b. fast red c. slow red
Which of the following statements about smooth muscle is correct: Select one: O a. Endothelial secretion of NO results in relaxation of blood vessel wall smooth muscle O b. Its activity is not affected by nervous system c. In smooth muscle cells myosin is deactivated by myosin light chain kinase O d. Its contraction is weaker than the contraction of skeletal muscle
The Sarcolemma in skeletal muscle is OA. Equivalent to the cell membrane which covers the entire fiber. OB. A Large multi-nucleated array of myofibrils, essentially one large fused cell. OC.

Which of the following statements is FALSE regarding skeletal muscle contraction? O a. Calcium binds troponin specifically on a calcium binding site which then leads to tropomyosin movement O b. The action potential of a motor nerve is transmitted to a muscle fibre through the neuromuscular junction which is a fusion of nerve and muscle cell membranes O c. Fine motor movement/control is a result of recruiting smaller motor units O d. Calcium is pumped into storage soon after it is released to the cytoplasm
