Question

Quizplus · Accepted Answer

Abundant mitochondria are typically found in Type I skeletal muscle fibers, also known as slow-twitch fibers. These fibers rely on oxidative metabolism and have a high capacity for aerobic energy production. Type II fibers, or fast-twitch fibers, rely more on anaerobic metabolism and have fewer mitochondria.
