The light dependent reaction (light reaction) of photosynthesis:
Light energy and the synthesis of ATP, photolysis, oxygen and hydrogen.
(a) Light is absorbed by chlorophyll molecules (green) on membranes inside the chloroplast. This is the light trapping stage in which photons of light are absorbed by the chlorophyll and turned into chemical energy (electrons).(b) The chemical energy (electrons) is trapped in making ATP.
(c) Photolysis: water used in photosynthesis is split which provides hydrogen for the formation of organic molecules (C6H12O6) in the light independent reaction. Oxygen gas is given off.
