The oxygen produced during the light-dependent reactions is the oxygen that is released by producers into the atmosphere. This is the oxygen that we and other consumers use for cellular respiration.

Enzymes in chloroplasts oxidize water molecules, meaning they remove electrons from water molecules. Then they use the gained electrons from water in conjunction with a photon of sunlight to produce high-energy electrons. These are capable of being transferred and used in the production of glucose in the dark reactions for the photosynthetic organism. Oxygen is the by-product of this oxidation of water.
