Different substrates get oxidised during respiration. How does Respiratory Quotient (RQ) indicate which type of substrate, i.e., carbohydrate, fat or protein is getting oxidised?
`R.Q.=(A)/(B)`
What do A and B stand for?
What tpye of substrates have R.Q.of `1,lt1orgt1?`

Explanation

### Step-by-Step Solution:

1. **Understanding Respiratory Quotient (RQ)**:
- The Respiratory Quotient (RQ) is a measure that indicates the type of substrate being oxidized during respiration. It is defined as the ratio of the volume of carbon dioxide (CO₂) produced to the volume of oxygen (O₂) consumed.

2. **Defining A and B**:
- In the formula RQ = A/B:
- **A** stands for the volume of carbon dioxide evolved (produced) during respiration.
