Abstract
ONE-ELECTRON oxidation–reduction reactions have been established in several enzymatic reactions, and electron transport has been found to be necessary in phosphorylation and mitochondrial systems1–4. The role of semiquinone radicals as active agents in biochemical electron transfer reactions has been indicated1,2, and correlations between the redox potential of the quinones and their effectiveness in catalysing a particular type of phosphorylation reaction have been suggested1,2,5. This principle has never been demonstrated quantitatively by chemical kinetics.
