Glycolysis flux

WebTo functionally assess astrocyte glycolytic flux in vitro, we measured the extracellular acidification rate (ECAR, a marker of glycolysis and lactate export) before and after glucose injection. E4 astrocytes displayed significantly higher ECAR after addition of glucose compared to E3 astrocytes, as well as a higher glycolytic capacity ... WebMar 1, 2024 · Namely, ATP is required in the upper glycolysis, while it is gained in the lower part of the glycolysis. Therefore, if the upper glycolytic flux surpasses over the lower glycolytic flux during the transient metabolism, the cell encounters the problem of energy shortage, and endangers the survival (van Heerden et al., 2014). This risk can be ...
