photolysis The part of photosynthesis that occurs in the granum of a chloroplast where light is absorbed by chlorophyll, turned into chemical energy, and used to split apart the oxygen and hydrogen in water. The oxygen is released as a byproduct while the reduced hydrogen acceptor makes its way to the second stage of photosynthesis, the Calvin cycle.
