Which of the following is a characteristic of slow-twitch oxidative skeletal muscle fibers?
A) long contraction duration only
B) few mitochondria only
C) high capillary density only
D) long contraction duration and high capillary density
E) long contraction duration, few mitochondria, and high capillary density

Question

Quizplus · Accepted Answer

Slow-twitch oxidative skeletal muscle fibers have a long contraction duration due to their high density of mitochondria, which allows for efficient aerobic energy production. They also have a high capillary density, which ensures a steady supply of oxygen and nutrients to the muscle fibers during prolonged activity. However, they do not have few mitochondria, as indicated in option E.
