Higher respiratory quotient is in which among the following?

Options

A. Fats
B. Protein
C. Carbohydrates
D. Organic acids

Answer

To solve the question regarding which substance has a higher respiratory quotient (RQ), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Respiratory Quotient (RQ)**:
- RQ is defined as the ratio of the volume of carbon dioxide produced to the volume of oxygen consumed during respiration. It is a measure of the type of substrate being metabolized.

2. **Identify the RQ Values for Different Substrates**:
- The RQ values for various substrates are as follows:
- Fat: RQ = 0.7
- Protein: RQ = 0.9
- Carbohydrate: RQ = 1.0
- Organic Acids: RQ = 1.4

3. **Compare the RQ Values**:
- Now, we compare the RQ values obtained:
- Fat (0.7)
- Protein (0.9)
- Carbohydrate (1.0)
- Organic Acids (1.4)

4. **Determine the Highest RQ**:
- Among the given options, the highest RQ is 1.4, which corresponds to organic acids.

5. **Conclude the Answer**:
- Therefore, the answer to the question "Higher respiratory quotient is in which among the following?" is **organic acids**.
