Abstract
Evidence is available showing that the coupling efficiency of the proton pump in cytochrome c oxidase of mitochondria can under certain conditions decrease significantly below the maximum attainable value. The view is developed that slips in the proton pump of cytochrome c oxidase represent an intrinsic switch mechanism which regulates the relative contribution of energy transfer and respiratory protection against oxygen toxicity by the oxidase.Keywords
