Comments p.97 box 1 2nd paragraph: "For each part, [investigators] can define surface efficiency as the number of ATP/s produced from a given amount of membrane area. The electron transport chain-independent part requires only glucose transporters (48 ± 10 nm^2/dimer), which can supply a maximum of 180 ± 40 glucose/s that each yield 4 ATP in both respiration and acetate fermentation. This gives a surface efficiency of 15 ± 5 ATP/s/nm^2."
