Question

Quizplus · Accepted Answer

Photorespiration is a wasteful process that occurs in plants when the rate of oxygen uptake exceeds the rate of carbon dioxide uptake, which can happen in hot and dry conditions. In photorespiration, oxygen is taken up by the plant and carbon dioxide is released, which wastes energy in the form of ATP and reduces the efficiency of photosynthesis. Therefore, photorespiration generates carbon dioxide and consumes ATP and oxygen.
