| Front | What are the stages of the light dependent reaction |
|---|---|
| Back | light striking the chlorophyll leads to photoionization and the electron becomes excited Electrons lost by chlorophyll are replaced by the electrons produced from the photolysis of a water molecule which produces hydrogen ions and oxygen. Some of the energy from the electrons released from the chlorophyll is used to actively transport protons into the thylakoids using a proton pump. The actively transported protons create a concentration gradient on the thylakoid side and the hydrogen ions are transported through the ATP synthase channel. The hydrogen ions are taken up by an electron carrier NADP and becomes reduced to form NADPH |
