Question (English)
Match the nutrient/condition with its Respiratory Quotient (RQ):
| Column A (Nutrient / Condition) | Column B (RQ Value) |
|---|---|
| 1. Protein | (a) < 0.7 |
| 2. Fat | (b) 1 |
| 3. Carbohydrate | (c) 0.7 |
| 4. Rapidly fattening hogs | (d) > 1 |
| 5. Fasting / Hibernating animal | (e) 0.8 |
- 1-e, 2-c, 3-b, 4-d, 5-a ✓ Correct
- 1-b, 2-c, 3-e, 4-d, 5-a
- 1-c, 2-e, 3-b, 4-d, 5-a
- 1-e, 2-b, 3-c, 4-d, 5-a
Explanation:
Correct Answer: 1-e, 2-c, 3-b, 4-d, 5-a
RQ = CO₂ produced ÷ O₂ consumed.
| Nutrient / Condition | RQ / Reason |
|---|---|
| Protein | 0.8 — mixed amino acid oxidation; incomplete combustion |
| Fat | 0.7 — H-rich, O-poor; more O₂ needed per CO₂ |
| Carbohydrate | 1.0 — C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O (RQ = 6/6 = 1) |
| Rapidly fattening hogs | > 1 — converting carbohydrate to fat releases extra CO₂ |
| Fasting/Hibernating animal | < 0.7 — oxidising stored body fat; minimal carbohydrate oxidation |
