Schematic representation of the mitochondrial respiratory chain. After permeabilization of the cells with digitonin, the electron flow through the different complexes was measured. Complex I NADH reductase. Complex II succinate dehydrogenase. Complex III cytochrome c reductase. Complex IV cytochrome c oxidase. Complex V ATP synthase. MDH malate dehydrogenase. GOT glutamate-oxaloacetate transaminase
