Answer

In the light reactions stage, energy from sunlight is absorbed by chlorophyll and converted into chemical energy. This takes the form of electron carrier compounds like ATP and NADPH. In the thylakoid membranes, PS I and PS II harness the light energy. In the light-independent reactions, carbohydrates are produced from carbon dioxide by using the chemical energy that was generated from the light reactions.
