Abundant mitochondria is typical of which type of skeletal muscle fibers?

Question

Quizplus · Accepted Answer

Type I skeletal muscle fibers are characterized by their high oxidative capacity and endurance. They have a high concentration of mitochondria, which are responsible for producing energy through aerobic metabolism. Therefore, abundant mitochondria are a typical feature of Type I fibers. Type II fibers, on the other hand, have a lower oxidative capacity and rely more on anaerobic metabolism to produce energy. They typically have fewer mitochondria.
