Question

Quizplus · Accepted Answer

Photorespiration is a process that occurs when the concentration of CO2 in the leaf is low and oxygen is in excess. It involves the addition of oxygen to ribulose-1,5-bisphosphate and the formation of the products 3-phosphoglycerate and 2-phosphoglycolate. This process is considered wasteful because it leads to the loss of carbon and energy for the plant. Therefore, it is best to minimize photorespiration in order to maximize photosynthesis.
