Explain the role of yeast m the preparation of alcohol.

Explanation

**Step-by-Step Text Solution:**

1. **Introduction to Yeast and Alcohol Preparation**: Yeast is a type of fungus that plays a crucial role in the production of alcohol through a process called fermentation.

2. **Understanding Fermentation**: Fermentation is a metabolic process where yeast cells convert sugars into alcohol and carbon dioxide. This process occurs in anaerobic (absence of oxygen) conditions.

3. **Conversion of Sugars**: The primary function of yeast in alcohol production is to convert sugars, which can come from various sources like fruits or grains, into ethanol (the type of alcohol) and carbon dioxide. The chemical equation for this process can be simplified as:
