Solution
The process described is photorespiration.
Photorespiration is a metabolic pathway in plants that consumes oxygen (O2), ATP, and releases carbon dioxide (CO2). It occurs when the enzyme RuBisCO oxygenates RuBP, instead of carboxylating it. This process reduces the efficiency of photosynthesis by diverting energy from the Calvin cycle and releasing CO2 that could otherwise be fixed.
