ROX and non-mitochondrial respiration
Residual oxygen consumption (ROX) is sometimes referred to as 'non-mitochondrial respiration'. This may be correct to a large extent, but is not entirely accurate. In a preparation of purified isolated mitochondria, a small but significant ROX is observed, even after correction for instrumental background oxygen flux. In this case, ROX is 'mitochondrial non-ETS' rather than ‘non-mitochondrial’ respiration. In permeabilized and intact cells, ROX may be higher than in isolated mitochondria, and this increased part then would actually be the non-mitochondrial component of ROX.
