Why is photorespiration considered as a wasteful process? Explain.

Explanation

### Step-by-Step Solution:

1. **Definition of Photorespiration**:
- Photorespiration is a process that occurs in plants, primarily in C3 plants, where the enzyme Rubisco reacts with oxygen instead of carbon dioxide. This leads to a series of reactions that ultimately release carbon dioxide.

2. **Role of Rubisco**:
- Rubisco is the enzyme responsible for the fixation of carbon dioxide in the Calvin cycle. It has dual activity: it can act as a carboxylase (fixing CO2) or an oxygenase (fixing O2).
