title: [Uncoupled oxidation in rat heart mitochondria].
abstract: Isolated heart mitochondria possessing a high phosphorylation efficiency with pyruvate and malate as substrates oxidize NADH and ascorbate unassociated with ADP phosphorylation. This uncoupled pathway is expressed partially when succinate or NAD-linked substrates are oxidized. The uncoupled oxidation is likely to be the result of the presence of a mitochondrial population with the high-permeable inner membrane in intact tissues. The nature and origin of a uncoupled respiratory system and its role in the thermoproduction of endotherms are discussed.
