In photosynthesis, light dependent and independent reactions are the two set of
reactions that occur.
In light-dependent reactions, the energy from sunlight is absorbed by

molecules like ATP and NADPH.
In light-independent reactions (the Calvin cycle), carbohydrate molecules are
assembled from carbon dioxide using the chemical energy harvested during the
light-dependent reactions.
