When NADP + and a suitable enzyme are present, two ferredoxin molecules, carrying one electron each, transfer two electrons to NADP +, which picks up a proton (i.e., a hydrogen ion) and becomes NADPH. As the electron passes along these proteins, energy from the electron fuels membrane pumps that actively move hydrogen ions against their concentration gradient from the stroma into the thylakoid space. c) Succinate dehydrogenase.
