... reduction proton transfer respiratory chain Electron flow along mitochondrial respiratory chains is dependent on a constant supply of oxygen, which provides the final sink for the electrons by being reduced to water. In mammalian mitochondria, this oxygen-reducing function is catalysed...

... constitute an alternative sink for electrons from the N. meningitidis respiratory chain. A partial denitrification pathway is encoded by the aniA nitrite reductase gene and the norB nitric oxide reductase gene. Analysis of the completed genome sequences of two N. meningitidis strains is used to generate...

...P.R. Rich Keilin's classic paper of 1925 [Keilin (1925) Proc. R. Soc. London Ser. B 100 , 129–151], achieved with simple, but elegant, techniques, describes the cytochrome components of the respiratory chain and their roles in intracellular respiration and oxygen consumption. Since that time...
