Baker’s yeast is

Options

A. Rhizopus stolonifer
B. Zygosaccharomyces
C. Saccharomyces cerevisiae
D. Saccharomycodes Ludwig

Explanation

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks about Baker's yeast, specifically its scientific name and its role in baking.

2. **Define Baker's Yeast**: Baker's yeast is a type of yeast used in baking. It is a unicellular fungus that plays a crucial role in the fermentation process.

3. **Scientific Name**: The scientific name of Baker's yeast is *Saccharomyces cerevisiae*. This name is important as it classifies the yeast within the scientific community.

4. **Role in Baking**: Baker's yeast is primarily used in the production of bread. During the baking process, it ferments the sugars present in the dough.

5. **Fermentation Process**: The fermentation carried out by Baker's yeast is anaerobic respiration. This means that it occurs without oxygen. The yeast converts sugars into ethanol and carbon dioxide.

6. **Effects of Fermentation**: The carbon dioxide produced during fermentation is responsible for the rising or puffiness of the bread. As the gas is trapped in the dough, it causes the bread to expand and become light and fluffy.

7. **Conclusion**: Therefore, Baker's yeast is scientifically known as *Saccharomyces cerevisiae*, and it is essential for making bread by producing carbon dioxide through fermentation.

**Final Answer**: Baker's yeast is *Saccharomyces cerevisiae*.
