Question

Quizplus · Accepted Answer

Photorespiration occurs when rubisco reacts with O₂ instead of CO₂. This occurs when the concentration of O₂ increases and the concentration of CO₂ decreases, such as during hot and dry conditions. This leads to the production of toxic byproducts, which the plant must then expend energy to get rid of.
