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. 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 metabolic pathway that occurs in plants, where oxygen is taken up and carbon dioxide is released, often occurring when the enzyme RuBisCO reacts with oxygen instead of carbon dioxide. This process generally results in the loss of fixed carbon and reduces the efficiency of photosynthesis, especially under high light and low carbon dioxide conditions. It serves as a way for plants to protect themselves from excessive light energy and helps to balance the process of ... Photorespiration is a process that occurs in plants. It happens when the enzyme Rubisco oxygenates RuBP, leading to a wasteful pathway.
