Bicarbonates 124-128 glucose-6-phosphate isomerase Oryctolagus cuniculus 22-25 7864155-11 1995 Initial rate of luminal Na(+)-dependent net acid extrusion in presence of CO2/HCO3- was approximately 229 microM/s (pHi 6.92), approximately 1.8 times higher than the flux of approximately 127 microM/s (P < 0.005) obtained in absence of CO2/HCO3- (pHi 6.66). Bicarbonates 78-82 glucose-6-phosphate isomerase Oryctolagus cuniculus 116-119 7864155-12 1995 CO2/HCO3- alkali-shifted the flux vs. pHi relationship by 0.3-0.4 pH units. Bicarbonates 4-8 glucose-6-phosphate isomerase Oryctolagus cuniculus 38-41 7864155-15 1995 Also, Na(+)-independent net acid extrusion rate was approximately two to three times higher in presence than in absence of CO2/HCO3- at comparable pHi. Bicarbonates 127-131 glucose-6-phosphate isomerase Oryctolagus cuniculus 147-150 7864155-17 1995 Stimulation of luminal Na+/H+ exchange and Na(+)-independent acid extrusion appears to be the major, if not the entire, explanation for the higher steady-state pHi caused by bilateral addition of CO2/HCO3-. Bicarbonates 200-204 glucose-6-phosphate isomerase Oryctolagus cuniculus 160-163
