Light stage/light dependent stage - this takes place only in the presence of light. It occurs in the grana areas of the chloroplasts. Light energy is used to split water molecules into Hydrogen atoms and oxygen atoms. Since light energy is used to split the water molecules, the reaction is known as photolysis.
2H2O(l)….>O2(g)+ 4H•
Dark stage/light independent stage/Calvin cycle this reaction occurs in the stroma, the reaction doesn't require light. It utilize Hydrogen atoms and ATP from the light reaction. The energy in the ATP is used to combine Carbon IV oxide with Hydrogen atoms to form glucose.
