Metabolic Water from Sugar Oxidation
Metabolic water produced by oxidation of 1 gram of sugar is:
- 0.60 g — Correct Answer
- 0.40 g
- 1.07 g
- None
Explanation:
Correct Answer: 0.60 g
Metabolic water is the water produced inside the body as a by-product of oxidative metabolism of nutrients. Oxidation of 1 g of glucose (sugar) yields 0.60 g of metabolic water.
Metabolic Water — Complete Table
| Substrate | Metabolic Water Produced per gram |
|---|---|
| Glucose / Sugar | 0.60 g |
| Starch | 0.56 g |
| Protein | 0.40 g |
| Fat | 1.07 g (highest — fat is most H-rich) |
Key Facts about Metabolic Water
- Metabolic water comprises 5–10% of total water intake
- Fat produces the most metabolic water (1.07 g/g) — important for desert animals like camels
- Metabolic water = water released from oxidative phosphorylation reactions
Why Other Options Are Wrong
- 0.40 g → metabolic water from protein oxidation, not sugar
- 1.07 g → metabolic water from fat oxidation, not sugar
- None → incorrect; metabolic water values are well-established
