WebAug 10, 2024 · Rubisco (ribulose 1,5- bis -phosphate carboxylase) is specific to the BS cells of C4 leaves. This enzyme accumulates abundantly in the chloroplasts of C3 species and represents as much as 50% of the total soluble proteins [ 46] or 20% of leaf nitrogen [ 47 ]. WebIn photorespiration, RuBisCO catalyses the oxygenation of RuBP to one molecule of PGA and phosphoglycolate. Q.5.What is the difference between photosynthesis and photorespiration? Sol. Photosynthesis and …

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. WebThe evolutionary adaptations eventually led to the formation of what is known as the “Rubiscosome”—a multifaceted complex of proteins which support Rubisco formation and function ( Erb and Zarzycki, 2024 ). …
