9. CO2 combines with the phosphorylated 5-carbon sugar ribulose bisphosphate (RUBP) reaction is catalyzed by the enzyme ribulose bisphosphate carboxylase oxygenase ( RUBISCO ) resulting 6-carbon compound breaks down into two molecules of 3-phosphoglyceric acid ( PGA ). PGA molecules are further phosphorylated (by ATP ) and are reduced (by NADPH ) to form phosphoglyceraldehyde ( PGAL ). Enzyme responsible for fixing 200 bilion tons of CO2 anually
10. Phosphoglyceraldehyde (PGAL) serves as the starting material for the synthesis of glucose and fructose . Glucose and fructose PolysaccharideSynthesis starch & cellulose Travel to other part of the plant As Monomer Sucrose
