WebFig. 4.Model for the pathway of electron and H + transfer in the cyt b 6 f complex based on the “Q cycle” model developed for the bc 1 complex. Major differences in the b 6 f complex are: (i) the presence of the additional heme, c n, coupled closely and tightly to heme b n; (ii) electron input into b 6 f through ferredoxin and perhaps FNR. Properties of heme cn are … WebCyanobacteria are photosynthetic microbes with highly differentiated membrane systems. These organisms contain an outer membrane, plasma membrane, and an internal system of thylakoid membranes...
