Question

Compared with slow fibers, fast fibers have a larger diameter, larger glycogen reserves, less myoglobin, and relatively fewer mitochondria?

1) True
2) False

Answer 1

Compared to slow fibers, fast fibers have a larger diameter, larger glycogen reserves, less myoglobin, and relatively fewer mitochondria. Slow fibers, on the other hand, are rich in capillaries, mitochondria, and myoglobin, allowing them to carry more oxygen and sustain aerobic activity for extended periods of time.

Step-by-step explanation:

Compared to slow fibers, fast fibers have a larger diameter, larger glycogen reserves, less myoglobin, and relatively fewer mitochondria. Fast fibers are designed for quick and powerful contractions, but they fatigue quickly. Slow fibers, on the other hand, are rich in capillaries, mitochondria, and myoglobin, allowing them to carry more oxygen and sustain aerobic activity for extended periods of time.
