Organelles associated with photorespiration are

Options

A. Chloroplast, mitochondria , Peroxisome
B. Chloroplast mitochondria , lysosome
C. Mitochondria , peroxisome , centrosome
D. Nucleus , centrosome peroxisome

Answer

### Step-by-Step Text Solution:

1. **Understanding Photorespiration**:
Photorespiration is a process that occurs primarily in C3 plants. It is considered a wasteful pathway because it competes with the Calvin cycle, which is essential for photosynthesis.

2. **Role of Rubisco**:
In the Calvin cycle, the enzyme ribulose bisphosphate carboxylase/oxygenase (Rubisco) typically catalyzes the reaction with carbon dioxide (CO2). However, during photorespiration, Rubisco can also react with oxygen (O2) instead of CO2, leading to the production of a compound that is not useful for the plant.

3. **Involvement of Organelles**:
Photorespiration involves a complex network of enzymatic reactions that facilitate the exchange of metabolites between different organelles. The key organelles involved in this process are:
- **Chloroplasts**: Where photosynthesis occurs.
- **Peroxisomes**: Involved in the breakdown of the byproducts of photorespiration.
- **Mitochondria**: Where the energy production occurs and also plays a role in the metabolism of the byproducts.

4. **Identifying the Correct Organelles**:
From the options provided, we need to identify which organelles are associated with photorespiration. The correct combination is:
- **Chloroplast**
- **Peroxisome**
- **Mitochondria**

5. **Conclusion**:
Therefore, the organelles associated with photorespiration are chloroplasts, peroxisomes, and mitochondria.
