Figure 6From: Including metabolite concentrations into flux balance analysis: thermodynamic realizability as a constraint on flux distributions in metabolic networksEquilibrium constants perturbation analysis for the E. coli network. Each bar shows the relative frequency of the 15 most frequently occurring alternative flux distributions (y-axis) in dependence on the standard deviation of the perturbation (x-axis) of the equilibrium constants. The less frequently occurring solutions are summarized in the bar designated by 'rest'.Back to article page
