Scaling features of membrane properties with cell size.

(a) Relationship between the total outer surface area of mitochondria and that of the plasma membrane for all species with available data. Diagonal lines denote three idealized ratios of the two. (b) The number of ATP synthase complexes per cell scales with cell surface area (S, in μm2) as 113S1.26 (r2=0.99). (c) Relationship between the total (inner + outer) surface area of mitochondria and cell volume for all species with available data. Open points are extrapolations for species with only outer membrane measures, derived by assuming an inner:outer ratio of 4.6, the average of observations in other species. References to individual data points are provided in Appendix 1–tables 1 and 2.
The number of ribosomes per cell scales with cell volume (V, in μm3) as 7586V0.82 (r2 = 0.92; SEs of the intercept and slope on the log scale are 0.13 and 0.05, respectively).

Color coding as in previous figures. The data presented in this figure can be found in Figure 2—source data 1; see also Appendix 1–table 3.
Appendix 1—figure 1
Relative contribution of ATP (P) and NADH/NADPH/FADH2 (H) to the biosynthetic costs of lipids and amino acids.

(A) Nonreduced costs including opportunity cost of precursors; (B) Reduced costs without precursors. Amino acid values are obtained from Akashi and Gojobori (2002), assuming growth on glucose.


Table 1
Contributions of membranes to total cellular growth costs.

Ot denotes the green alga Ostreococcus tauri, Sc the yeast Saccharomyces cerevisiae, Ds the green alga Dunaliella salina, and Ss the pig (Sus scrofa) pancreas cell; references given in Supplementary material. Cell volumes and total membrane areas are in units of μm3 and μm2, respectively, with the latter excluding membranes associated with the plastids in the algal species. The fraction of the total cell growth budget allocated to membranes is obtained by the ratio of Equations (1b) and (4), using the species-specific reduced costs in Table 1 where available, and otherwise applying the averages for eukaryotic species; this total cost is then apportioned into five different fractional contributions in the following lines.

Appendix 1—table 4
Costs of lipids.

The average cost per molecule is calculated for a variety of species using estimates of lipid compositions from the literature and the formulas described in the text. The fraction of fatty acids of given length and saturation level is not shown. Cardiolipin costs are assumed to be 637 (evolutionary) and 236 (reduced) ATP. The cost for molecules in the ‘other’ category is assumed to be the average of glycerophospholipids (GPL) in the species and cardiolipin.
