The enzyme that converts glucose into alcohol is

Options

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

Answer

To determine the enzyme that converts glucose into alcohol, we can follow these steps:

### Step-by-Step Solution:

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

2. **Understand the Role of Yeast**: Yeast is a microorganism that performs anaerobic respiration, meaning it converts glucose into alcohol in the absence of oxygen.

3. **Identify the Products**: During fermentation, glucose (C6H12O6) is converted into ethanol (C2H5OH) and carbon dioxide (CO2). The reaction can be summarized as:
\[ \text{Glucose} \rightarrow \text{Ethanol} + \text{Carbon Dioxide} \]

4. **Identify the Enzyme**: The enzyme responsible for this conversion in yeast is called **zymase**. Zymase is a complex of enzymes that facilitates the fermentation process.

5. **Eliminate Other Options**:
- **Lipase**: Breaks down lipids into fatty acids and glycerol.
- **Diastase**: Converts starch into maltose.
- **Invertase**: Breaks down sucrose into glucose and fructose.

6. **Conclusion**: Therefore, the enzyme that converts glucose into alcohol is **zymase**.

### Final Answer:
The enzyme that converts glucose into alcohol is **zymase**.
