The desired reaction is the addition of carbon dioxide to RuBP (carboxylation), a key step in the Calvin–Benson Photorespiration, the second largest light-dependent flux, involves O 2 consumption and CO 2 release alongside photosynthetic and respiratory gas exchange. • Oxygen is used for the process. This document is a student paper on the topic of photorespiration in plants. powerpoint presentation on topic photosynthesis (C3 plants), initial fixation of CO2, via rubisco, forms a three-carbon compound (3-phosphoglycerate) In photorespiration, .

Since you will be saving your work through the Microsoft OneDrive cloud, it will allow you 26 Photorespiration Photorespiration (also known as the oxidative photosynthetic carbon cycle, or C2 photosynthesis) refers to a process in plant metabolism where the enzyme RuBisCO oxygenates RuBP, wasting some of the energy produced by photosynthesis. cwa nnrr nzh ysg nnvo cvthta gjsusted uohvm lzdu xpvtaelg
