Which enzyme convertes sucrose into ethanol

Options

A. Diastase
B. Invertase
C. Zymase
D. Both (b) and (c)

Explanation

To determine which enzyme converts sucrose into ethanol, we can break down the process into steps:

### Step-by-Step Solution:

1. **Understanding Sucrose**:
- Sucrose is a disaccharide composed of glucose and fructose. Its chemical formula is C12H22O11.

2. **Hydrolysis of Sucrose**:
- Sucrose can be hydrolyzed into its monosaccharide components, glucose (C6H12O6) and fructose (C6H12O6), in the presence of an enzyme called **invertase** (or sucrase). The reaction can be summarized as:
\[ \text{C}_{12}\text{H}_{22}\text{O}_{11} + \text{H}_2\text{O} \xrightarrow{\text{invertase}} \text{C}_6\text{H}_{12}\text{O}_6 \text{ (glucose)} + \text{C}_6\text{H}_{12}\text{O}_6 \text{ (fructose)} \]

3. **Fermentation of Glucose**:
- Once glucose is obtained, it can be converted into ethanol (C2H5OH) through fermentation. This process is facilitated by the enzyme **zymase**, which catalyzes the conversion of glucose into ethanol and carbon dioxide (CO2). The reaction can be summarized as:
\[ \text{C}_6\text{H}_{12}\text{O}_6 \xrightarrow{\text{zymase}} \text{C}_2\text{H}_5\text{OH} + \text{CO}_2 \]

4. **Conclusion**:
- Therefore, the enzyme that converts sucrose into ethanol is **zymase**, after the initial hydrolysis of sucrose by invertase.

### Final Answer:
The enzyme that converts sucrose into ethanol is **zymase**.
