Expert Answer
The light reaction of photosynthesis occurs in two main steps:
(1) Activation of chlorophyll - On exposure to light energy, chlorophyll becomes activated by absorbing photons.
(2) Splitting of water - The absorbed energy is used in splitting the water molecule into hydrogen and oxygen, releasing energy. This reaction is known as photolysis of water.
2H2O
4H+ + 4e- + O2
