Photorespiration is a metabolic process in plants that occurs when the enzyme RuBisCO oxygenates ribulose-1,5-bisphosphate instead of carboxylating it, leading to the consumption of energy and release of CO2. This process typically takes place under high light intensity and low carbon dioxide concentrations, which can negatively impact plant productivity by reducing the efficiency of photosynthesis.
congrats on reading the definition of Photorespiration. now let's actually learn it.
