In photorespiration, from the chloroplast, the glycolate is diffused to peroxisome, where it is oxidised to

Options

A. Serine
B. Glycerate
C. Glycine
D. Glyoxylate

Answer

### Step-by-Step Solution:

1. **Understanding Photorespiration**: Photorespiration is a process that occurs in plants where oxygen is consumed and carbon dioxide is released, leading to a wasteful pathway that does not produce ATP or sugars.

2. **Formation of Glycolate**: During photorespiration, the enzyme Rubisco catalyzes the reaction between ribulose 1,5-bisphosphate and oxygen, resulting in the formation of two molecules: phosphoglycerate and phosphoglycolate. The phosphoglycolate is then converted into glycolate.

3. **Diffusion to Peroxisome**: The glycolate produced in the chloroplast diffuses into the peroxisome, which is another organelle within the plant cell.

4. **Oxidation in Peroxisome**: Inside the peroxisome, glycolate undergoes oxidation. The oxidation of glycolate leads to the formation of glyoxylate.

5. **Conclusion**: Therefore, the glycolate that diffuses from the chloroplast to the peroxisome is oxidized to glyoxylate.

### Final Answer:
In photorespiration, from the chloroplast, the glycolate is diffused to the peroxisome, where it is oxidized to **glyoxylate**.
