摘要
The model of Wilson and co-workers (D. F. Wilson, C. S. Owen, and A. Holian, 1977, Arch. Biochem. Biophys. 182, 749-762) for the regulation of mitochondrial oxidative phosphorylation has been extended to include the dependence on oxygen tension. The derived rate expression correctly describes the observed dependence of cellular energy metabolism on oxygen tension, including the oxygen dependence at normoxic" physiological values. Experimental evidence is presented that oxidative phosphorylation by suspensions of isolated rat liver mitochondria is also dependent on oxygen concentration up to values of at least 100 μM. © 1979."
