In higher plants, there is the potential for spatial separation of cyclic electron flow, in the nonappressed membranes, from linear flow, between PSII in the appressed membranes and PSI in the grana margins two major functions for cyclic electron flow are presumed.
Under strong illumination, cyclic electron flow increases, generating a large proton gradient required for the formation of nonphotochemical quenching (NPQ) within the antenna, protecting PSII against excess light.
