Abstract

Photophosphorylation by was inhibited by lipophilic cations and the energy-transfer inhibitors diphenylphosphorylazide, Dio-9, 4-chloro-7-nitrobenzofurazan and chlorhexidene. Membrane-bound ATPase activity was also inhibited by these energy-transfer inhibitors. The formation of a membrane potential was stimulated approximately 1.7-fold on illumination, rising to a value between −110 and −150 mV. The sensitivity of the processes producing this membrane potential to uncouplers, energy-transfer inhibitors and 2-heptyl-4-hydroxyquinoline--oxide was measured in the light and the dark.
