Zymase was isolated from

Options

A. Zea mays
B. Saccharomyces sp
C. Aspergillus niger
D. Rhizopus sceinus

Answer

**Step-by-Step Solution:**

1. **Understanding Zymase**: Zymase is an enzyme complex that plays a crucial role in the fermentation process. It catalyzes the conversion of sugars into ethanol and carbon dioxide.

2. **Historical Context**: The enzyme was first discovered by Edward Buchner in 1897, who isolated it from yeast cells.

3. **Source of Zymase**: The question asks where Zymase was isolated from. It is important to note that Zymase is primarily found in yeast cells.

4. **Identifying the Correct Organism**: Among the options provided (Ziamase, Saccharomyces, Aspergillus niger, and Rhizopus), we need to identify which one is associated with yeast. Saccharomyces is a genus of fungi that is commonly known as yeast.

5. **Conclusion**: Since Zymase is isolated from yeast cells and Saccharomyces is the correct representation of yeast, the answer to the question is Saccharomyces.

**Final Answer**: Zymase was isolated from Saccharomyces.
