The energy absorbed from light is transferred to two kinds of energy-storing molecules. Chlorophyll is a pigment that plays an important role in photosynthesis. When both wavelengths are used, electrons can pass from photosystem II to photosystem I generating more ATP. The carbon dioxide in the water is transformed into glucose, which is a sugar, and the water is transformed into oxygen. The fluid portion of the chloroplast, outside of the thylakoids, is known as the stroma. Based on a variety of experiments, it is known that the rate of photosynthesis is highest when wavelengths of light between 400 and 500 nm are used, and when wavelengths around 700 nm are used.
