Kinetic effect of calcium on oxidative phosphorylation intermediate respiration. A: Relationship between ΔGATPe and Jo with and without calcium. B: Michaelis-Menten relationship between Jo and ADP with and without calcium. The open square and open circle signify the ADP values reported for human skeletal muscle at rest and during moderate exercise, respectively. C: Eadie-Hofstee plot for the relationship between Jo and ADP where y= -(KmADP)x + Vmax. Filled squares – calcium, open diamonds – no calcium. Error bars signify standard error. n = 12. Slopes, regression analyses, and the resultant p-values for A and C are reported in Table 2 under ΔGATPe and KmADP, respectively.
