How are the light-dependent and light-independent reactions of photosynthesis related?

1 Answer

Light independent reactions depend on light dependent reaction for supply of APT, NADPH.


  1. Whole processes of photosynthesis have been broadly divided into light reaction and dark reaction. The light reaction is completed in the grana of chloroplast in presence light, while the dark reaction is completed in stroma in light and dark both.
  2. In light reations, ATPs, NADPHs and oxygen as by product is produced. These products i.e., ATPs, and NADPHs are utilized in dark reaction or light indepndent reactions for the reduction of carbon dioxide into glucose. Thank you
