||p.97 box 1 2nd paragraph: "The surface efficiency of the electron transport chain-dependent part can be estimated from experimental electron transport chain protein structures, abundances, and kinetics (Valgepea et al., 2013, Etzold et al., 1997). Normalizing abundances
to the terminal ATP synthase, an estimated 84 nm^2 of electron transport chain is required to generate 270 ± 40 ATP/s, the
maximum speed of ATP synthase (Etzold et al., 1997), resulting in a surface efficiency of only 3 ± 1 ATP/s/nm^2 (Tables S1B and S1D). The electron transport chain stoichiometry shown in the table below represents averages across growth rates (Valgepea et al., 2013) (Table S1B)."
