Question

The muscle cells perform anaerobic respiration when we run very fast. This means that anaerobic respiration is more efficient than aerobic respiration.

• A. True
• B. False

Answer 1

The correct option is B

False

Respiration that occurs in the absence of oxygen is known as anaerobic respiration. The oxygen content in the body exhaust really fast when we run fast and the muscle cells are forced to perform anaerobic respiration. In this type of respiration, the food molecules are not broken down completely and the energy released is also very less. But in aerobic respiration, the food molecules are broken down completely and the energy released is more. So we can summarise that aerobic respiration is more efficient than aerobic respiration.
