what is nadph in photosynthesis
NADPH. During the Light Dependent Cycle of photosynthesis, light is absorbed by the chlorophyll. The electrons are excited, which starts them moving from one enzyme to another. A hydrogen atom attaches itself to an NADP molecule, converting it to NADPH.oth the ATP and the NADPH are used to convert the carbohydrates created in the Light Dependent Cycle to C-C bond energy. This is done in the Light Independent Cycle, or the dark reaction cycle.
