Fast twitch muscle fibers are better than slow twitch fibers for short iterations of energy such as sprinting or jumping. This is true because

A. fast twitch fibers primarily perform anaerobic respiration
B. have more myosin than slow twitch fibers
C. endure contraction for longer periods of time
D. have more mitochondria than slow twitch fibers

Respuesta :

Answer:

A. fast twitch fibers primarily perform anaerobic respiration.

Explanation:

Fast twitch fibers are helpful in generating quick energy from anaerobic respiration during exercise, sprinting or jumping. Anaerobic respiration is a type of respiration in which energy is released from glucose molecules in the absence of oxygen by the mitochondria of the cell. The energy which is produced produced is very low as compared to aerobic respiration.
