The step in photosynthesis that does not need light is when water splits into hydrogen and oxygen. This step, known as photolysis or the light-dependent reactions, occurs in the presence of light and is responsible for the production of oxygen. The other steps, such as carbon dioxide and hydrogen combining to make glucose, chlorophyll absorbing energy, and oxygen being released, all require light energy.
