Photorespiration produces

Options

A. Sugar but not ATP
B. ATP but no sugar
C. Both ATP and Sugar
D. Neither ATP nor sugar.

Answer

**Step-by-Step Solution:**

1. **Understanding Photorespiration**: Photorespiration is a process that occurs in plants, primarily when the concentration of oxygen is high and carbon dioxide is low. It is often considered a wasteful pathway because it does not lead to the production of energy-rich compounds.

2. **Organelles Involved**: Photorespiration takes place in three organelles: chloroplasts, peroxisomes, and mitochondria. Each of these organelles plays a specific role in the process.

3. **Inputs Required**: During photorespiration, carbon dioxide (CO2) is fixed. This process requires energy, which is typically derived from ATP and NADPH produced during photosynthesis.

4. **Outputs of Photorespiration**: Unlike regular respiration or photosynthesis, photorespiration does not produce ATP or sugar. Instead, it leads to the consumption of energy and does not yield any useful products for the plant.

5. **Conclusion**: Given that photorespiration does not produce ATP or sugar, the correct answer to the question "Photorespiration produces" is "neither ATP nor sugar."
