Which one of the following pairs is WRONGLY matched ?

Options

A. Fruit juice - pectinase
B. Textile - amylase
C. Detergents - lipase
D. Alcohol - nitrogenase

Answer

To determine which pair is wrongly matched, we will analyze each enzyme and its corresponding industry application:

1. **Pectinase - Fruit Juices**:
- Pectinase is an enzyme that helps in clarifying fruit juices. It breaks down pectin, a substance that can cause cloudiness in juices. Therefore, this match is correct.

2. **Amylase - Textile**:
- Amylase is an enzyme that breaks down starches into sugars. In the textile industry, it is used in the process of desizing fabrics, making this match also correct.

3. **Lipase - Detergents**:
- Lipases are enzymes that break down fats and oils. They are commonly used in detergents to help remove oily stains from fabrics. Thus, this match is correct as well.

4. **Nitrogenase - Alcohol**:
- Nitrogenase is an enzyme that facilitates the fixation of atmospheric nitrogen into ammonia, which is essential for plants. However, nitrogenase is not involved in the production of alcohol. Therefore, this match is incorrect.

Based on the analysis above, the wrongly matched pair is **Nitrogenase - Alcohol**.

### Final Answer:
The wrongly matched pair is: **Nitrogenase - Alcohol**.
