RQ of proteins, carbohydrates, fats and organic acids are in order

Options

A. `lt 1,1, lt 1, gt 1`
B. `gt 1, lt 1, 1, 1`
C. `1, 1, 0, -1`
D. `0, lt 1,1, gt 1`

Answer

To determine the order of the respiratory quotient (RQ) values for proteins, carbohydrates, fats, and organic acids, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Respiratory Quotient (RQ)**:
The respiratory quotient is defined as the ratio of carbon dioxide produced (CO2) to oxygen consumed (O2) during respiration. It gives insight into which macronutrients are being metabolized.

2. **Identify RQ Values for Each Macronutrient**:
- **Fats**: The RQ value for fats is approximately **0.7**.
- **Proteins**: The RQ value for proteins is approximately **0.8**.
- **Carbohydrates**: The RQ value for carbohydrates is **1.0**.
- **Organic Acids**: The RQ value for organic acids is approximately **1.3**.

3. **Arrange the RQ Values in Order**:
Based on the values identified:
- Fats: 0.7
- Proteins: 0.8
- Carbohydrates: 1.0
- Organic Acids: 1.3

Thus, the order from lowest to highest RQ is:
- Fats (0.7) < Proteins (0.8) < Carbohydrates (1.0) < Organic Acids (1.3)

4. **Conclusion**:
The order of RQ values for proteins, carbohydrates, fats, and organic acids is:
- Fats < Proteins < Carbohydrates < Organic Acids

### Final Answer:
The order of RQ values is: **Fats (0.7) < Proteins (0.8) < Carbohydrates (1.0) < Organic Acids (1.3)**.
