Mitochondrial conditions determine the degree of reduction of each carrier in the respiratory chain. For example, when NADH and , are abundant, tlu steady-state degree of reduction of the carriers decreases as electrons pass from the substrate too, When electron transfer is blocked, the carriers before the block become more reduced and those beyond the block become more oxidined. Match the state of oxidation for ubiquinone (C) and cytochrome, 1.6,4, and as with each mitochondrial condition. Abundant NADH and Oy, but cyanide added only canken under de los contented.
