half-maximal oxidation of cytochrome c occurred at 2.0 microm o2 in treated cells incubated under state 3 conditions , whereas in intact cells it was 6.0 microm and in isolated mitochondria ( state 3 ) 0.69 microm . the intermediate value for treated cells indicates that both the geometry of mitochondrial packing and the intracellular diffusion coefficient are important in determining intracellular mitochondrial o2 dependence .
