Botany - Photosynthesis in Higher Plants Question with Solution | TestHub

In C₃plants, some O₂does bind to RuBisCO, and hence CO₂ fixation is decreased. Here the RuBP instead of being converted to 2 molecules of PGA binds with O₂to form one molecule of phosphoglycerate and phosphoglycolate (2 Carbon) in a pathway called photorespiration. In the photorespiratory pathway, there is neither synthesis of sugars, nor of ATP. Rather it results in the release of CO₂with the utilisation of ATP. In the photorespiratory pathway there is no synthesis of ATP or NADPH.
