This reaction is known as the photolysis of water. The oxygen is evolved as a byproduct. In this light dependent reactions, the light energy absorbed is used for the splitting of water molecules and it is also conserved as ATP and NADPH which are used to drive the carbon fixation reactions of photosynthesis.
