End product of fermentation of sugars is

Options

A. Water and carbon dioxide
B. Alcohol and carbon dioxide
C. Carbon dioxide
D. Alcohol.

Answer

### Step-by-Step Solution:

1. **Understanding Fermentation**:
- Fermentation is a type of anaerobic respiration, which means it occurs in the absence of oxygen.

2. **Initial Breakdown of Glucose**:
- During fermentation, glucose is first broken down into pyruvic acid. This process occurs in the cytoplasm of the cell.

3. **Conversion of Pyruvic Acid**:
- The pyruvic acid is then converted into acetaldehyde. This is a crucial step in the fermentation process.

4. **Final Products of Fermentation**:
- The acetaldehyde is further converted into ethanol (alcohol) and carbon dioxide. This is the final step in the fermentation of sugars.

5. **Identifying the End Products**:
- The end products of the fermentation process of sugars are therefore ethanol and carbon dioxide.

6. **Choosing the Correct Option**:
- Based on the above steps, the correct answer to the question "End product of fermentation of sugars is" is **alcohol and carbon dioxide**.

### Final Answer:
The end product of fermentation of sugars is **alcohol and carbon dioxide**.
