Fermentation of glucose by the yeast cells produces ………………. and …………… .

Explanation

To answer the question about the fermentation of glucose by yeast cells, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Fermentation**: Fermentation is a metabolic process that occurs in the absence of oxygen (anaerobic conditions). Yeast cells, particularly Saccharomyces cerevisiae, are commonly used in this process.

2. **Starting Material**: The process begins with glucose, a simple sugar that serves as the primary energy source for yeast cells.
