Glycolysis flux
WebApr 14, 2024 · As anticipated, measuring the extracellular acidification rate (ECAR), a proxy measure of glycolysis, that glucose deprivation significantly decreased glycolytic flux in HepG2 cells (Fig. 2B). WebModel simulations suggest that most of the glycolytic flux feeds pyruvate synthesis. Indeed, the pentose phosphate pathway (PPP) accounts for less than 1% of the total glycolytic flux . From pyruvate, the metabolic flux is distributed either to lactate or to the TCA cycle. Interestingly, P4 cells direct more than 50% of their glycolytic flux to ...
