Explain why an abundance of mitochondria in slow-oxidative fibers is correlated with an abundance of capillaries.
A)Increased delivery of oxygen is needed for sustained ATP production.
B)They are both needed to produce the color of the slow-oxidative fibers.
C)Myosin ATPase needs increased ATP production.
D)Large diameter fibers enable more room for mitochondria, which in turn require more capillaries.

Question

Quizplus · Accepted Answer

Slow-oxidative fibers rely on aerobic respiration for ATP production, which requires a continuous supply of oxygen. An abundance of mitochondria enhances ATP production, while an abundance of capillaries ensures sufficient oxygen delivery to support this process.
