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 a metabolic process in plants that occurs when the enzyme RuBisCO fixes oxygen (O₂) instead of carbon dioxide (CO₂). It leads to the release of CO₂ and consumption of ATP, thus reducing photosynthetic efficiency. This process links to the Calvin Cycle and reveals how plants adapt under hot, dry, and low-CO₂ conditions. Photorespiration is a process that occurs in plants when carbon dioxide concentration is low and RuBisCO reacts with oxygen instead of carbon dioxide. Learn about the causes, effects and mechanisms of photorespiration, and how some plants have evolved to avoid it. Photorespiration is a process that occurs in plants. It happens when the enzyme Rubisco oxygenates RuBP, leading to a wasteful pathway.
