Which one of the following pairs is wrongly matched pair of the enzyme and its commercial use?

Options

A. Detergents - Lipase
B. Alcohol - Nitrogenase
C. Fruit juice - Pectinase
D. Textile - Amylase

Explanation

To solve the question of identifying the wrongly matched pair of enzyme and its commercial use, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Enzymes and Their Uses**:
- **Lipases**: Used in detergents to remove oily stains and also in flavoring cheese.
- **Nitrogenase**: Associated with nitrogen metabolism, specifically nitrogen fixation.
- **Pectinases**: Used in fruit juices to clarify them by breaking down pectin.
- **Amylases**: Used in textile industries to degrade starches for the separation and desizing of textile fibers.

2. **Analyze Each Option**:
- **Option 1**: Lipases in detergents - This is correctly matched as lipases help in removing oily stains.
- **Option 2**: Alcohol nitrogenase - This is incorrectly matched. Nitrogenase is not related to alcohol production; the correct enzyme for alcohol metabolism is alcoholic dehydrogenase.
- **Option 3**: Pectinases in fruit juices - This is correctly matched as pectinases clarify juices.
- **Option 4**: Amylases in textile industries - This is correctly matched as amylases help in processing textiles.

3. **Conclusion**:
- The only wrongly matched pair is **Option 2: Alcohol nitrogenase**.

### Final Answer:
The wrongly matched pair of the enzyme and its commercial use is **Option 2: Alcohol nitrogenase**.
