Options

A. 1
B. 2
C. infinity
D. 0

Answer

To solve the question regarding the value of RQ (Respiratory Quotient) during anaerobic respiration when alcohol is produced, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Anaerobic Respiration**:
- Anaerobic respiration occurs in the absence of oxygen. In this process, glucose is partially broken down to produce energy, along with byproducts such as alcohol (ethanol) and carbon dioxide.

2. **Identify the Reaction**:
- The general equation for anaerobic respiration producing alcohol (ethanol) is:
\[ C_6H_{12}O_6 \rightarrow 2 C_2H_5OH + 2 CO_2 + \text{energy} \]
- Here, glucose (C₆H₁₂O₆) is converted into ethanol (C₂H₅OH) and carbon dioxide (CO₂).

3. **Define RQ (Respiratory Quotient)**:
- RQ is defined as the ratio of the volume of carbon dioxide produced (CO₂) to the volume of oxygen consumed (O₂):
\[ RQ = \frac{CO_2 \text{ produced}}{O_2 \text{ consumed}} \]

4. **Determine CO₂ and O₂ Values**:
- In anaerobic respiration producing alcohol:
- CO₂ produced = 2 (from the reaction)
- O₂ consumed = 0 (since it is anaerobic)

5. **Calculate RQ**:
- Substituting the values into the RQ formula:
\[ RQ = \frac{2}{0} \]
- Division by zero is undefined, which is conventionally represented as infinity.

6. **Conclusion**:
- Therefore, the value of RQ during anaerobic respiration when alcohol is produced is **infinity**.

### Final Answer:
- The value of RQ in anaerobic conditions producing alcohol is **infinity** (Option C).
