1. Light Dependent Reaction Objectives ò Understanding the processes of photoionisation, photophosphorylation & photolysis. ò Knowledge of where these processes take place. ò Knowledge of the difference between cyclic & non-cyclic phosphorylation.

2. Overview of photosynthesis

4. Photosystems

6. Electron Transfer

8. òThe energy changes of electrons as they flow through the light reactions are analogous to the cartoon. òAs complicated as the scheme is, don’t lose track of its functions: òThe light reactions use solar power to generate ATP and NADPH which provide chemical energy and reducing power to the sugar making reactions.
