Fitted parameters of the “rate” and “relative rate” models used to fit the pO2 data (Equations 14 and 17 or 20).

Control experiments (row 1) were fitted to a straight line. Values are means ± SD for each parameter. Values in italics are the means of the 95% confidence intervals. P* = initial PO2, q1 = initial consumption rate, α2 = proportionality constant from “rate” model, αr = true proportionality constant (Equation 18), q2 = consumption rate at equilibrium. The p-value reports the significance of the one-way ANOVA test to compare the values among the groups. The Bonferroni t-test was used to compare the multiple pairs among the groups if the ANOVA test showed a significant difference.** p* p
