About: Flux Balance Analysis (FBA) finds steady-state metabolic fluxes that maximize a cellular objective (typically ATP or biomass production) subject to stoichiometric constraints and flux bounds. In this simplified network, glucose is phosphorylated to G6P, enters glycolysis producing pyruvate and ATP, then feeds the TCA cycle (aerobic) or is converted to lactate (anaerobic). O₂ availability controls the aerobic/anaerobic switch — Warburg effect in cancer cells shifts toward lactate even with O₂.
