Abstract

Biological oxidation is the mechanism by which oxygen is supplied to living organisms and energy is produced. These processes involve the participation of oxygen incorporated into the substrates by oxidoreductase enzymes. The mechanisms of reaction of enzymes involved in both oxidation-reduction processes and electron transport chain mitochondrial-ETC, and their relationship with reactive oxygen species (ROS) production, are presented here.


Keywords: Dehydrogenases, Hydroperoxidases, Mitochondrial Electron Transport Chain-ETC, Oxidases, Oxidoreductases, Oxygenases, Redox potential, ROS.
