Question

A high respiratory quotient indicates:

1. A. Absence of respiration
2. B. Aerobic respiration (Correct answer)
3. C. Anaerobic respiration
4. D. Inhibition of respiration

Correct Answer

Option B — Aerobic respiration

Detailed Solution & Explanation

The correct answer is Aerobic respiration.

Key Points

• Respiratory Quotient (RQ) = CO2 produced / O2 consumed.
• RQ > 1 indicates anaerobic respiration (lactic acid fermentation produces CO2 without consuming O2).
• RQ = 1 for carbohydrates, < 1 for fats.
