Results are shown for simulations of varied substrate availability of glucose, acetoactate, lactate and 6 different fatty aicids: palmitate, stearate, oleate, alpha-linoleate, eicosapentaenoate and docosahexaenoate. For each simulated composition efficiency values $\left(C_{i^{+}}\right)$ were calculated based on three criteria q_j (j=1,2,..,nj): (1) oxygen requirement ( $\left(v_{O_2}\right)$
