(Assume 1 ATP is produced for each pair of electrons used to form NADPH.). NADH – NADPH without an extra phosphate group, used mostly in catabolic reactions. What does NADPH mean? Most of the ATP in a cell is made in the mitochondria, the cell's powerhouse. Search. The fixation phase occurs when (3)CO2 is fixed to (3)RuBP by rubisco to form 3-phosphoglycerate (6)3PGA. However, neglecting the very minute difference in ΔG0, the 105 times higher relative amount of NADPH works out to a difference of ~30 kJ/mol in actual relative ΔG. The Calvin cycle using ATP faster than NADPH so need a method of making ATP without making NADPH. the hydrogen atom is nadph is made by. During cellular respiration, the cells use these coenzymes to turn fuel from food into energy. The energy from this electron drives the formation of NADPH from NADP + and a hydrogen ion (H +).
