Answer: These ATP molecules are used in light independent reactions to reduce carbon dioxide to form sugars.
Explanation: Photosynthetic reactions are divided into two parts: the light dependent reactions and the light independent reactions. In light reactions, sunlight is absorbed by chlorophyll and other photosynthetic pigments and conserved as chemical energy. The light reactions of photosynthesis generate two energy-rich molecules: ATP and NADPH. These products are use in the light independent reactions or carbon fixation reactions to drive the reduction of carbon dioxide to trioses (3- carbon sugars) and more complex compounds such as glucose.
