What is the net outcome of the photorespiratory pathway in C ₃ plants?

Step-by-step solution

In the photorespiratory pathway, RuBisCO binds with O₂ instead of CO₂ , forming one molecule of phosphoglycerate and phosphoglycolate. During this process, there is neither synthesis of sugars nor of ATP. Rather, it results in the release of CO₂ with the utilisation of ATP. Therefore, the net outcome of photorespiration is the release of CO₂ and the consumption of ATP, making it a wasteful process. Answer: Release of CO ₂ with the utilization of ATP
