1 Recently we have proposed and presented evidence suggesting the existence of a "bi-trans-membrane" electron transport chain, located at the contact sites between outer and inner mitochondrial membranes, which can be utilized to promote either the oxidation of exogenous NADH in the presence of catalytic amounts of added cytochrome c or the reduction of exogenous cytochrome c supported by the oxidation of respiratory substrates present inside the mitochondria.

3 In the out-->in electron transport pathway the components involved appear to be cytosolic reduced substrates-->NADH produced by cytosolic dehydrogenases activity-->NADH-cytochrome b5 oxidoreductase complex leaning out the external side of the external membrane-->exogenous cytochrome c-->cytochrome oxidase of contact sites-->molecular oxygen. NAD cytochrome c, somatic Homo sapiens
