    Oxygenic photosynthesis is the process used by plants, algae and some photosynthetic bacteria. During this process carbon dioxide is reduced to a carbohydrate and electrons are removed from water, releasing oxygen into the air. Anoxygenic photosynthesis is performed by specialized bacteria. During this process the light energy is used to remove electrons from other sources, not water. These sources include hydrogen gas, hydrogen sulfide and iron compounds. Therefore instead of releasing oxygen, other compounds such as sulfur are released during this process.
