Answer:
Formation of ATP and NADPH
Explanation:
During the light reaction of photosynthesis, one molecule of each of ATP and NADPH is formed and these serve as precursor for the light-independent reaction of photosynthesis. The process occur in the chloroplast of plants and can be summarized below:
- Chlorophyll within the chloroplast absorbs light, leading to the excitement of electrons within its photosystems
- The excited electrons are released from the photosystems
- Water molecules is split to release electrons, H+ and oxygen. The electrons replace those lost by the photosystems due to excitation
- The excited electrons released by photosystems enter into the electron transfer chain and reduce NADP+ to NADPH
- The build up of H+ creates a gradient that ATP synthase enzyme uses to synthesize ATP from ADP.
