(a) Hypoxia and the resultant decreased pHe induced by different routes including production and export of H+ and lactate (through up-regulation of NHE1, MCT4), conversion of CO2 to carbonic acid, influx of the dissociated weak base HCO3− while H+ is left outside, etc., (b); glucose metabolism in mammalian cells involving aerobic glycolysis metabolism (i.e., Warburg effect).
