WebG3P is a 3 carbon molecule, and you need 5 carbons to make RuBP. Simply put, plants use multiple G3P together to make a RuBP C-C-C-c-c that's 1 RuBP c-C-C-C-c that's 2 RuBPs c-c-C-C-C that's 3 RuBPs Note: whenever I change from capital C to lower case c, it indicates the use of a new G3P molecule. WebGlyceraldehyde-3-phosphate dehydrogenase (GAPDH) and phosphoribulokinase (PRK) are two enzymes of the Calvin Benson cycle that stand out for some peculiar properties they have in common: (i) they both use the products of light reactions for catalysis (NADPH for GAPDH, ATP for PRK), (ii) they are both light-regulated through thioredoxins and (iii) they …
