WebMar 17, 2024 · In the dark, Rubisco is inhibited by the binding of sugar phosphate–like molecules that are removed from Rubisco active sites upon the RCA-driven, light-induced conformational change of the enzyme. RCA, on the other hand, requires ATP to function and is inhibited by the ADP formed upon Rubisco activation. WebRuBisCO's primary function is photosynthesis and photorespiration. It catalyzes the first step in the C3 pathway or Calvin cycle, namely the carboxylation of RuBP. It leads to the production of two 3-PGA molecules. RuBisCO also has an affinity for oxygen, thus it binds to some O 2 during the photorespiration process.
