16972982 Liu L, Li Y, Li H, Chen J: Significant increase of glycolytic flux in Torulopsis glabrata by inhibition of oxidative phosphorylation. FEMS Yeast Res. 2006 Dec;6(8):1117-29.

One was separately adding, at 10 mg L1, specific inhibitors of complex I (rotenone) or of the bc1 complex (antimycin A) to the culture broth of T. glabrata CCTCC M202019, which resulted in significantly decreased intracellular ATP levels (43% and 27.7%) and significantly increased rates of glucose consumption (qs) and pyruvate production (qp); another approach was breeding a respiratory-deficient mutant RD-16, in which cytochromes aa3 and b in the ETC were deleted after ethidium bromide mutagenesis, to reduce the ETC activity constitutively.
With the two strategies, the specific activity of phosphofructokinase (R2=0.9971), the average specific glucose consumption rate (R2=0.9967) and the average specific pyruvate production rate (R2=0.965) were closely correlated with the intracellular ATP level, all of them being increased at a lower intracellular ATP level.

The effects of calcium antagonists nimodipine, nicardipine and flunarizine on lactate production and specific activities of some enzymes regulating glycolytic flux have been evaluated in synaptosomes isolated from rat whole brain and submitted to in vitro chemical hypoxia induced by rotenone, an inhibitor of mitochondrial respiration.
The following enzymes have been tested; hexokinase (ATP: D-hexose-6-phosphotransferase, EC2.7.1.1), phosphofructokinase (ATP: D-fructose-6-phosphate 1-phosphotransferase, EC 2.7.1.11) and pyruvate kinase (ATP: pyruvate 2-O-phosphotransferase, EC 2.7.1.40).

Addition of rotenone markedly enhanced glycolysis at all pHe values studied.
