ABSTRACT
The mitochondrial oxidative phosphorylation involves five multimeric complexes imbedded in the inner membrane complex I (Nicotinamide Adenine Dinucleotide (NADH) quinone oxidoreductase), II (succinate dehydrogenase), III (ubiquinol cytochrome c oxido reductase or bc1 complex), IV (cytochrome c oxidase), and V (ATP synthase). These respiratory complexes are conserved from the yeast Saccharomyces cerevisiae to human with the exception of complex I, which is replaced by three NADH dehydrogenases in S. cerevisiae. Here, we provide several protocols allowing an exhaustive characterization of each yeast complex this chapter describes procedures from mitochondria preparation to measurement of the activity of each complex and analysis of their subunit composition and provides information on the interactions between different complexes.
