Figure 5

Numerical simulation showing the effect of substrate affinity (parameter K in Equation 2) and free energy values on the steady-state biomass composition. The colour mapping indicates biomass of species X2 as fraction of total biomass. The y axis shows the K1 of species X1, while K2 for species X2 is fixed at 10 × 10−6. The x axis shows the free energy of metabolic conversion reaction for species X1, while that of species X2 is always set to be 5 kJ (mol Substrate)−1 lower (i.e, thermodynamically more favourable) than that for species X1.
