During photosynthesis, light excites electrons in the photosystems and it is used to generate ATP and NADPH.
Photosynthesis is a series of chemical reactions used by plants to generate carbohydrates by means of light energy (solar radiation).
During this process, light excites electrons in the photocenters and this energy can be converted to chemical energy via ATP and NADPH production.
In conclusion, during photosynthesis, light excites electrons in the photosystems and it is used to generate ATP and NADPH.
