name: cyclic photophosphorylation in photosystem I
namespace: biological_process
def: "An electron begins in P700, passes from the primary acceptor to ferredoxin, then to a complex of two cytochromes (similar to those found in mitochondria), and then to plastoquinone before returning to chlorophyll. This transport chain produces a proton-motive force, pumping H+ ions across the membrane; this produces a concentration gradient which can be used to power ATP synthase during chemiosmosis. This pathway produces neither O2 nor NADPH." [http://en.wikipedia.org]
