Summary of results and comparisons of nonlinear regression based determinations of H₂O₂ metabolism by muscle mitochondria respiring on 5 mM succinate.

Parameter
VP (nmol H2O2 g protein−1 s−1)	17.4±1.8a
k (s−1 g protein −1 l)	0.037±0.003b
[H2O2]ss (nmol l−1)	484±28

^ap<0.05 for paired t-test compared to measured $V_{app}^P$ of 12.7±1.48 nmol H₂O₂ g protein⁻¹ s⁻¹.

^bWithin 95% confidence interval (0.031–0.059) for k based on regression of k_app as $V_{app}^P$ approaches zero for uninhibited mitochondria (Fig. 3B).
