In light-dependent reactions, the energy from sunlight is absorbed by chlorophyll and converted into chemical energy in the form of electron carrier molecules like ATP and NADPH.Light energy is harnessed in Photosystems I and II, both of which are present in the thylakoid membranes of chloroplasts.In light-independent reactions (the Calvin cycle), carbohydrate molecules are assembled from carbon dioxide using the chemical energy harvested during the light-dependent reactions.
TERM[ edit ]
photosystem
Either of two biochemical systems active in chloroplasts that are part of photosynthesis.
