Talk about the carried out processes of photosynthesis.

Chlorophyll molecules absorb light energy to synthesize energy-rich molecules ATP and NADPH used for plant metabolism (the light dependent phase of photosynthesis). The chemical energy contained in these molecules allows, through a series of reactions, the carbon sequestration from atmospheric carbon dioxide to form carbohydrates (the dark phase or Calvin cycle). The overall reaction of photosynthesis is: 6 CO2 + 12 H2O → C6H12O6 + 6 H2O + 6 O2.
