Muscle fibers differ in speed, power, and duration of muscle contraction. The speed of the muscle contraction is based on the expression of fast or slow genetic variation of myosin ATPase. The fast variants are known as fast-twitch fibers and slow variants are known as slow-twitch fibers.

Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.

An athlete participates in aerobic exercise three times a week. One of the changes is an increased ability to deliver oxygen to her skeletal muscles. Over time she notices that she can continue the exercise with greater intensity and duration. The reason for this change is that there is a(n) a. greater response from phosphate transfer. b. greater production of ATP from glycolysis and less from aerobic cellular respiration. c. greater production of ATP from aerobic cellular respiration. d. increased production of lactate.

Which of the following statements correctly describes why white muscle fibers do not need is mini mitochondria as red muscle fibers? a) want muscle fibers use anaerobic respiration which does not occur in the mitochondria b) what muscle fibers use anaerobic respiration which requires more efficient mitochondria than aerobic respiration c) white muscle fibers get more oxygen than the red muscle fibers
