The process of conversion of sugar into alcohol is called ________.

Options

A. nitrogen fixation
B. moulding
C. fermentation
D. infection

Answer

**Step-by-Step Solution:**

1. **Understanding the Process**: The question asks about the conversion of sugar into alcohol. This process is a biochemical reaction that involves microorganisms.

2. **Identifying the Microorganism**: The main microorganism responsible for this conversion is yeast. Yeast cells are known to ferment sugars.

3. **Defining Fermentation**: Fermentation is a type of anaerobic respiration, which means it occurs in the absence of oxygen. During fermentation, yeast converts sugar into alcohol and carbon dioxide.

4. **Chemical Equation**: The general equation for fermentation can be represented as:
\[ \text{Sugar} \rightarrow \text{Alcohol} + \text{CO}_2 \]

5. **Choosing the Correct Term**: Given the options provided, the process of converting sugar into alcohol is specifically called "fermentation."

6. **Final Answer**: Therefore, the answer to the question is: The process of conversion of sugar into alcohol is called **fermentation**.
