Assessment of two <em>in vitroem> assays to detect mitochondrial toxicity in HepG2 cells.
Measurement of mitochondrial respiration, glycolysis and reserve capacity by XFe96.
Potential mechanism of mitochondrial toxicity can be predicted using the extracellular flux assay.
Combining Glu/Gal and extracellular flux assays improves predictivity of mitochondrial toxicants.
