Enzymes that changes glucose to ethyl alcohol is

Options

A. Zymase
B. Diastase
C. Invertase
D. Maltase

Answer

To answer the question regarding the enzyme that converts glucose to ethyl alcohol, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Process**: The conversion of glucose to ethyl alcohol is a process known as fermentation. This process is primarily carried out by yeast.

2. **Understand the Role of Enzymes**: Enzymes are biological catalysts that speed up chemical reactions. In the case of fermentation, specific enzymes are responsible for breaking down glucose.

3. **Identify the Enzyme**: The enzyme responsible for the conversion of glucose to ethyl alcohol is called **zymase**. Zymase is a complex of enzymes found in yeast that facilitates the fermentation process.

4. **Differentiate from Other Enzymes**:
- **Diastase**: Converts starch into maltose.
- **Invertase**: Breaks down sucrose into glucose and fructose.
- **Maltase**: Converts maltose into glucose.
- These enzymes do not convert glucose to ethyl alcohol, thus confirming that zymase is the correct answer.

5. **Conclusion**: Therefore, the enzyme that changes glucose to ethyl alcohol is **zymase**.

### Final Answer:
The enzyme that changes glucose to ethyl alcohol is **zymase**.
