HOverview of the light-dependent reaction

- Light energy is absorbed by chlorophyll in the photosystems - It excites electrons in the chlorophyll, releasing them from mol. - Chlorophyll has been photoionised - Some energy released by electrons used to add a phosphate to ADP to form ATP - Some used to form reduced NADP - ATP transfers energy, reduced NADP transfers H to the light-independent reaction - During process H2O is oxidised to O2
