Question

question 32 (2 points) muscle fast - twitch and slow - twitch fibers differ in their number of mitochondria all of these differ between fast - twitch and slow - twitch fibers endurance color primary metabolic means of generating atp

Explanation:

Fast - twitch fibers have fewer mitochondria, lower endurance, are lighter in color, and rely more on anaerobic metabolism for ATP production. Slow - twitch fibers have more mitochondria, higher endurance, are darker in color, and use aerobic metabolism for ATP production. So all the listed factors differ between them.

Answer:

B. all of these differ between fast - twitch and slow - twitch fibers
