Light-dependent stage
Occurs on the thylakoid membranes.
Two main functions:
To produce ATP
To split water molecules, providing H+ ions to
reduce CO2 and produce carbohydrates…read more

Cyclic photophosphorylation
AT Electron e-
P acceptor
ADP + Pi Electron transport
chain light
2. The electron is taken up
by an electron acceptor
and passed along an
electron transport chain to
produce ATP.
1. When light hits a chlorophyll
molecule, a light-excited electron
leaves the molecule.

NADP stands nicotinamide
adenine dinucleotide
Light-independent stage
Occurs in the stroma.
Uses reduced NADP and ATP from the light-
