NADP+ is converted to NADPH during **photosynthesis **in the light-dependent stage. The process involves the use of light to energize electrons. These electrons then transfer their energy to NADP+ along with a hydrogen ion, leading to NADPH. ;
The light reaction transfers two electrons through the electron transport chain.
NADP + becomes NADPH through a reduction process in the light-dependent reactions of photosynthesis. This involves the absorption of light energy, water splitting, electron transport, re-energizing of electrons, and the addition of these electrons and protons to NADP + . As a result, NADPH is formed, which stores energy for the Calvin cycle.
