What is fermentation ? Name any two organic compounds produced in this process.

Explanation

### Step-by-Step Solution:

1. **Definition of Fermentation**:
- Fermentation is a metabolic process that occurs in the absence of oxygen, also known as anaerobic respiration. It involves the breakdown of glucose to produce energy when oxygen is not available.

2. **Process of Fermentation**:
- During fermentation, glucose undergoes glycolysis to produce pyruvic acid. In the absence of oxygen, pyruvic acid is then converted into other organic compounds through various biochemical reactions.
