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

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