WebJan 7, 2024 · This results in low net flux and very slow growth. Hence, for steady-state growth, the equilibrium must be broken and FBP ≫ PEP or FBP ≪ PEP, such that either glycolytic flux is bigger than gluconeogenic or vice versa (r ENO + ≫ r ENO-and r ENO + ≪ r ENO-, respectively). This is achieved by the irreversible reactions, which drain and ...
