What is the defination for photolysis and give its chemical equation?
The light-dependent splitting of water is called photolysis. It involves breaking of water molecule to form oxygen gas and hydrogen ions and electrons. The released electrons and hydrogen ions are captured by other substrate in the vicinity. for e.g in photosynthesis, they are captured by NADP to form NADPH.
