Abstract excerpt
In mitochondria isolated from the yeast Saccharomyces cerevisiae, under non-phosphorylating conditions, we have previously shown that there is a right of way for electrons coming from the external NADH dehydrogenase, Nde1p. In this work, we show that the electron competition process is identical under more physiological conditions i.e. oxidative phosphorylation. Such a competition generates a priority for...
