Glycolysis flux
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 ... WebThe specific mechanisms by which ME1 loss drives increased glycolytic flux remain to be fully explored and may relate not to only redox capacity but also a need to replenish intracellular pyruvate levels. To date, there is no evidence linking ME1 activity directly to macrophage polarization states.
