Photorespiration is a cyclic respiration process that happens in photosynthetic cells and results in CO2 removal. Photorespiration occurs most commonly in C3 plants such as beet, bean, cotton, rice, wheat, barley, and so on. Learn about photorespiration, a process that reduces the efficiency of photosynthesis in C3 plants. Find out how photorespiration occurs, what are its factors, how it differs from dark respiration and C4 cycle, and what are its advantages and disadvantages. 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.
