1.light reaction are also called as photo chemical phase.
2.the light dependent reaction takes place in chlorophyll containing thylakoids called grana of chloroplasts.
3.step-1 : the chlorophyll on exposure to light energy become activated by absorbing photons.
4.step 2 :the energy is used in splitting the water molecule into two component ions named hydrogen H plus, hydroxyl ions OH minus, this reaction is called photolysis.
5. step 3 : OH minus ions through a series of steps produce water H2O and O2.
6. the end products of light reaction are ATP, NADPH and O2
