Question

Where does photorespiration occur?

Answer 1

Photorespiration:

1. Photorespiration is the process in which plants lose fixed carbon as CO₂ when they are exposed to light.
2. The C₂ cycle is another name for photorespiration.
3. Peroxisomes initiate this process, which begins in chloroplasts.
4. Photorespiration is more common when the oxygen content is high.

Importance of photorespiration:

1. When stomata close throughout the day due to water stress, photorespiration aids in energy dissipation.
2. By using extra excitation energy, photorespiration shields the plant from photooxidative damage.
