Photolysis definition class 10
WebOct 23, 2024 · Photolysis: The light reaction initiates when the chlorophyll absorbs light. It causes one of its electrons to move to a higher energy state. The excited electron is transferred to an acceptor molecule and is replaced by an electron from water (H 2 O). It causes the decomposition of water into H + and OH –, hence termed as photolysis.
