What is a key difference between red muscle fibers and white muscle fibers?
| 1. | Red muscle fibers are adapted for endurance and have a high myoglobin content, while white muscle fibers are designed for short bursts of activity and contain less myoglobin. |
| 2. | White muscle fibers are rich in myoglobin, whereas red muscle fibers are not. |
| 3. | Red muscle fibers are smaller in diameter than white muscle fibers. |
| 4. | White muscle fibers have more mitochondria than red muscle fibers. |
