The oxygen by-product of photosynthesis is created by the splitting of <u>water</u> molecules to replace the electrons ejected from the reaction center of photosynthesis ii.

Photosynthesis is a process whereby organisms containing plastids like green plants and other microorganisms make glucose using carbon dioxide, water and energy from sunlight.

A significant by-product of this process is oxygen, used by animals for respiration. Photosynthesis is of two stages; the light stage, also called photosynthesis i and the dark stage, also called photosynthesis ii.

During the light stage, the energy from sunlight is used to split water molecule into electrons, hydrogen protons and oxygen. The electrons are transported by carriers and used up in the reaction center of photosynthesis ii, while the oxygen is given of as a by-product.
