Amino acid biosynthesis: Glutamate synthase requires NADPH that catalyzes the conversion of α-ketoglutarate and glutamine into two molecules of glutamate. Its role in G6PD deficiency. The function of NADPH is to supply electrons for some of the enzyme reactions. For example, when sugars are created during photosynthesis, carbon molecules are chained together using the energy from sunlight. Time Traveler for NADPH. NADP+ is the used form of NADPH, and must be reduced with more electrons and a hydrogen. It is the reduced form of NADP + and as such is a high energy molecule that helps drive the Calvin cycle.NADPH is formed during photosynthesis with the use of light energy in the electron transport chain of chloroplasts. If delivered by injection, NADH may cause injection site pain, swelling, and redness. Phagocytes use NADPH to generate reactive oxygen species: Neutrophil granulocytes (depicted) and macrophages put in bacteria and then fuse the endocytotic vacuole with granules that compose different sorts of antimicrobial molecules. 1. If absent, the H 2 O 2 would be converted to hydroxyl free radicals by … In the mesophyllic cells of the C4 plants,  malate dehydrogenase requires NADPH for the conversion of oxaloacetate to malate.
