[Reverse electron transfer from the cytochrome c level in cyanide-resistant mitochondria of the yeast, Candida lipolytica].
The ability of cyanide-resistant mitochondria of yeast Candida lipolytica to perform reverse electron transfer from cytochrome c to alternative oxidase was studied. It was shown that the energy for such a transfer can be provided by high energy intermediates or membrane potential but not by ATP. Reverse electron transfer from cytochrome c is impossible due to energy of NADH and alpha-glycerophosphate oxidation via alternative pathway in the presence of cyanide. These results prove once again that electron transfer via alternative pathway is not connected with the energy accumulation.
