What is Photorespiration?
Photorespiration is the metabolic process occurred during the Calvin cycle. Photorespiration is also known as C2 Cycle. RuBisCO is the major enzyme in photorespiration. Photorespiration mainly occurs in the C3 plants to take care of the wasteful activity of RuBisCO.
During the Photorespiration mechanism, O2 is needed and CO2 is released in the presence of light.
Photorespiration is exactly the same as the respiration process because in both reactions O2 is used and CO2 is released.
Organelles involved in Photorespiration
3 cell organelles are involved in photorespiration those are:
- Chloroplast
- Peroxisomes
- Mitochondria
Photorespiration – Definition, Diagram, Process, Significance
Photorespiration is a plant metabolic process, most precisely in the cells of the leaves. Photorespiration is a wasteful pathway that competes with photosynthesis and can have negative effects on plant growth and productivity. Photorespiration is triggered when the concentration of carbon dioxide (CO2) in the leaf is low and the concentration of oxygen (O2) is high.
