RQ of 4, 1 and 0.7 occur in case of

Options

A. Malic acid, palmitic acid and tipalmitin
B. Oxalic acid, carbohydrate and tripalmitin
C. Tripalmitin, malic acid and carbohydrate
D. Palmitic acid, carbohydrate and oxalic acid

Answer

To solve the question regarding the respiratory quotient (RQ) values of 4, 1, and 0.7, we will analyze each RQ value and identify the corresponding substrates.

### Step-by-Step Solution:

1. **Understanding Respiratory Quotient (RQ)**:
- RQ is defined as the ratio of the volume of carbon dioxide (CO2) produced to the volume of oxygen (O2) consumed during respiration.
- RQ = (Volume of CO2 produced) / (Volume of O2 consumed)

2. **Identifying RQ Values**:
- Different substrates have characteristic RQ values:
- **Carbohydrates**: RQ = 1
- **Fats**: RQ = 0.7
- **Proteins**: RQ ≈ 0.9
- **Organic Acids**: RQ can vary, for example:
- **Malic Acid**: RQ ≈ 1.33
- **Succinic Acid**: RQ ≈ 1.41
- **Oxalic Acid**: RQ = 4

3. **Analyzing the Given RQ Values**:
- **RQ of 4**: This corresponds to **Oxalic Acid**.
- **RQ of 1**: This corresponds to **Carbohydrates**.
- **RQ of 0.7**: This corresponds to **Fats** (e.g., Tripalmitin).

4. **Conclusion**:
- The RQ values of 4, 1, and 0.7 correspond to:
- RQ of 4: **Oxalic Acid**
- RQ of 1: **Carbohydrates**
- RQ of 0.7: **Fats**

5. **Final Answer**:
- The correct substrates for the given RQ values are Oxalic Acid (4), Carbohydrates (1), and Fats (0.7).
