In the conversion of glucose and fructose to ethyl alcohol which of the following enzymes is used ?

Options

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

Answer

To solve the question regarding the enzyme used in the conversion of glucose and fructose to ethyl alcohol, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Process**: The conversion of glucose and fructose to ethyl alcohol (ethanol) occurs through fermentation. This is a biological process where sugars are converted into alcohol and carbon dioxide by the action of enzymes.

**Hint**: Remember that fermentation is a key process in the production of alcohol.

2. **Identify the Sugars**: Glucose and fructose are simple sugars (monosaccharides) that can be derived from sucrose (table sugar). The conversion of sucrose into glucose and fructose is facilitated by an enzyme.

**Hint**: Think about how sucrose is broken down into its constituent sugars.

3. **Enzyme for Sugar Breakdown**: The enzyme responsible for breaking down sucrose into glucose and fructose is called invertase. This enzyme catalyzes the hydrolysis of sucrose.

**Hint**: Invertase is crucial for converting sucrose into glucose and fructose.

4. **Fermentation of Sugars**: Once glucose and fructose are available, they undergo fermentation. This process is catalyzed by a complex of enzymes.

**Hint**: Consider what enzymes are involved in the fermentation process.

5. **Identify the Enzyme Complex**: The enzyme complex that catalyzes the fermentation of glucose and fructose into ethanol and carbon dioxide is known as zymase. Zymase is a collection of enzymes that facilitate the conversion of sugars into alcohol.

**Hint**: Zymase is specifically used for the fermentation of sugars into ethanol.

6. **Conclusion**: Therefore, the enzyme used in the conversion of glucose and fructose to ethyl alcohol is zymase.

**Final Answer**: Zymase.

### Summary:
The enzyme used in the conversion of glucose and fructose to ethyl alcohol is zymase, which catalyzes the fermentation process.
