Abstract

The reduction of Fe(CN)63- in the solution of outside liposome incorporating chlorophyll a was observed upon illumination with visible light under unaerobic condition. The photoreduction of Fe(CN)63- was enhanced by the presence of ion carrier, such as carbonylcyanide m-chlorophenylhydrazone, in the dispersion. The action spectrum of the photoreduction agreed with the absorption spectrum of chlorophyll a in liposome bilayer. The carrier-mediated proton transport was also observed upon illumination, occuring in the direction to compensate the excess charge produced by the photoinduced electron transport through the bilayer.
