Which of the following is formed during photorespiration ?

Options

A. Sugar cane
B. Phosphoglycolate
C. NADPH
D. ATP

Answer

**Step-by-Step Solution:**

1. **Understanding Photorespiration**:
- Photorespiration is a process that occurs in plants when the concentration of oxygen (O2) is high and the temperature is elevated. Under these conditions, instead of taking in carbon dioxide (CO2) for photosynthesis, plants take in O2 and release CO2.

2. **Role of RUBP**:
- Ribulose bisphosphate (RUBP) is a crucial molecule in this process. In normal conditions, RUBP combines with CO2 during the Calvin cycle. However, during photorespiration, RUBP reacts with O2 instead.

3. **Formation of Products**:
- When RUBP reacts with O2, it leads to the formation of two products: phosphoglycolate and phosphoglycerate.
- Phosphoglycolate is a two-carbon compound, while phosphoglycerate is a three-carbon compound.

4. **Identifying the Correct Answer**:
- Among the options given (sugarcane, phosphoglycolate, NADP, and ATP), we need to identify which one is formed during photorespiration.
- Since phosphoglycolate is one of the products formed during this process, it is the correct answer.

5. **Elimination of Other Options**:
- Sugarcane is a type of plant and not a product of photorespiration.
- NADP and ATP are not formed during photorespiration; in fact, the process does not produce any ATP or NADPH.

6. **Conclusion**:
- Therefore, the correct answer to the question "Which of the following is formed during photorespiration?" is **phosphoglycolate**.
