Abstract
With the in vitro calibration of isolated mitochondria, it has been shown that the redox state of heme a+a3 in cytochrome oxidase depends on both mitochondrial energy state and respiratory rate, but that of copper does not (1,2, 3). This finding, however, has not been confirmed in vivo living tissues, since hemoglobin absorption masks the redox change of heme a+a3 in the visible region.
