Involves only photo-system I (P 700)
light absorbed is passed to primary pigment.
e- from chlorophyll molecule passes to an excited state (photoactivation process)
excited electron is captured by e- acceptor and passed back to the chlorophyll molecule via a series of electron carriers
enough energy is released
synthesis of ATP from ADP occurs + synthesis of a an inorganic phosphate (chemiosmosis process)
ATP produced eventually passes to the light-independent / dark stage reactions
