SUMMARY The glucose analogue, 3‐O‐methyl glucose, is actively transported inwards at the plasmalemma of Hydrodictyon africanum. It is likely that a similar mechanism is operative for glucose influx, although demonstration of its active transport is complicated by an apparent coupling of the rates of glucose entry and metabolism. Active OMG Transport, and the influx and metabolism of glucose, need ATP. This ATP can be supplied, in order of increasing rates of the two processes, by fermentation, cyclic photophosphorylation, oxidative phosphorylation and by photo‐phosphorylation plus oxidative phosphorylation.
