1 Control pHi was 7.00 +/- 0.02 in HCO3(-)-containing solutions at an extracellular pH of 7.35. Bicarbonates glucose-6-phosphate isomerase Rattus norvegicus
2 The results are compatible with the presence of at least three different pHi-regulating mechanisms: a Na+/H+ antiporter, a Na(+)-dependent HCO3-/Cl- exchanger (both regulating pHi during a transient acidification), and a passive Cl-/HCO3- exchanger (regulating pHi during transient alkalinisation). Bicarbonates glucose-6-phosphate isomerase Rattus norvegicus
3 The results are compatible with the presence of at least three different pHi-regulating mechanisms: a Na+/H+ antiporter, a Na(+)-dependent HCO3-/Cl- exchanger (both regulating pHi during a transient acidification), and a passive Cl-/HCO3- exchanger (regulating pHi during transient alkalinisation).
