  • The light dependent reaction takes place in the thylakoid membranes of the chloroplasts. Here, light energy absorbed by photosynthetic pigments in the photosystems and converted to chemical energy.
  • The light energy is used to add a phosphate group to ADP to form ATP, and reduced NADP to form NADPH. ATP transfers energy and reduced NADP transfers hydrogen to the light-independent reaction.
  • During the light dependent reaction water is oxidised to oxygen.
  • Light energy absorbed is used to;
    1. Make ATP from ADP and inorganic phosphate. This is called photophosphorylation.
    2. Make NADPH from NADP
    3. Splitting water into protons, electrons and oxygen. This is called photolysis.
