Select the incorrect statement about photorespiration ?

Options

A. Photorespiration occurs in high light intensities
B. Photorespiration occurs in high temperature
C. Photorespiration occurs under high `O_(2)` concentration
D. Photorespiration occurs under high `CO_(2)` concentration

Answer

### Step-by-Step Solution:

1. **Understanding Photorespiration**:
- Photorespiration is a process that occurs in plants where the enzyme ribulose bisphosphate carboxylase/oxygenase (rubisco) reacts with oxygen instead of carbon dioxide. This typically happens when the concentration of oxygen is high relative to carbon dioxide.

2. **Identifying the Conditions for Photorespiration**:
- Photorespiration is more likely to occur under specific conditions:
- High oxygen concentration.
- High temperatures.
- High light intensity.
- However, it is important to note that photorespiration is not favored when carbon dioxide levels are high.

3. **Analyzing the Statements**:
- The question asks to select the incorrect statement about photorespiration.
- The statements to consider are:
- Photorespiration occurs at high light intensities.
- Photorespiration occurs at high temperatures.
- Photorespiration occurs under high oxygen concentration.
- Photorespiration occurs under high carbon dioxide concentration.

4. **Evaluating Each Statement**:
- **High Light Intensities**: This statement is generally true as photorespiration can occur under high light conditions.
- **High Temperatures**: This statement is also true as higher temperatures can increase the rate of photorespiration.
- **High Oxygen Concentration**: This statement is true because photorespiration is favored when oxygen levels are high.
- **High Carbon Dioxide Concentration**: This statement is incorrect because high carbon dioxide concentration would lead rubisco to favor carboxylation over oxygenation, thus reducing photorespiration.

5. **Conclusion**:
- The incorrect statement about photorespiration is that it occurs under high carbon dioxide concentration.

### Final Answer:
The incorrect statement about photorespiration is: **Photorespiration occurs under high carbon dioxide concentration.**
