Comparison of the physiological data with predictions of the mathematical model for the addition of graded levels of extracellular CO₂/HCO₃⁻. A: maximal rates of pH_i change (negative direction) produced by the addition of extracellular CO₂/HCO₃⁻. B: maximal changes in pH_S (positive direction) caused by the addition of extracellular CO₂/HCO₃⁻. The physiological data are taken from Fig. 10 of the first paper in this series (14) and Fig. 10 of the 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. 9 of the present paper.
