Photosynthesis takes place in chloroplasts of green plants and algae and results in the conversion of radiant energy into chemical energy. Water and carbon dioxide are the raw materials; plants can produce sugars by using chlorophyll and light energy. During the first reaction of photosynthesis, ATP and NADPH are produced from light energy. Oxygen and hydrogen are released from water broken during the light reaction. In the dark reaction, CO2 is converted into glucose by consuming energy that comes from first step of photosynthesis.
