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.
