Summarize how chemical energy is formed from light energy during photosynthesis

Actually the energy of light is absorbed by the chlorophyll molecules. They then pass it to the reaction centres wherein the photon energy is utilized to split the water molecules. The H+ produced is used to generate a gradient where the enzymes employ the electrical gradient from chemiosmosis and to convert ADP into ATP. Other molecules such as NADPH are formed and are used to reduce CO2 to other organic molecules.
