Comparison of the physiological data with predictions of the mathematical model for the addition and removal of extracellular 1.5% CO₂/10 mM HCO₃⁻. A: maximal rates of pH_i change (negative or positive direction) produced by the addition or removal of extracellular CO₂/HCO₃⁻. B: maximal changes in pH_S (positive or negative direction) caused by the addition or removal of extracellular CO₂/HCO₃⁻. The physiological data come from Fig. 2 of the first paper in this series (14) and Fig. 3 of second paper (15). Note that here we report the means ± standard deviation (and not SE, as in the previous two papers). The data for model predictions come from Fig. 6 of the present paper.
