Mitochondrial oxygen affinity, respiratory flux control and excess capacity of cytochrome c oxidase
... A low flux control coefficient is directly related to the threshold effect and explains why COX can be inhibited to a large extent without effect on flux through the respiratory chain (Letellier et al. 1993, 1994). The ...
