Light dependent reaction produces ATP and NADPH.

In the light dependent reaction the in PS II the photosynthetic pigments capture photons and transfer electrons. The electron transport triggers a proton pump. The protons move across the membrane of the pigments to form ATP. Then the electrons are transfered to PS II and the electrons get excited by the photons. Again similar process continues to reduce NADP+ and produce NADPH
