Question

Choose the correct statement regarding white muscle fibres.

• A. Depends on aerobic process for energy.
• B. Possesses plenty of mitochondria
• C. Contains less quantity of myoglobin
• D. Contains less amount of sarcoplasmic reticulum

Answer 1

Answer:

C. Contains less quantity of myoglobin

• White muscle fibers contain less myoglobin than red muscle fibers.

• Myoglobin is a protein that stores oxygen for muscle contractions, and it gives muscles their red color.

• White muscle fibers have less myoglobin because they rely on anaerobic glycolysis for energy production, rather than aerobic processes that require oxygen.
