Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.
Light with a wavelength of 500 nm (blue-green light) can stimulate photosynthesis even though blue-green light is not absorbed by chlorophyll. This lead to the discovery of carotenoids, which absorb blue-green light and transfer the energy of their excited electrons to chlorophyll.
