EC1- Oxidoreductases. Oxidoreductases are enzymes that catalyse both oxidation and reduction processes. These enzymes function as hydrogen donors while oxidising a substrate. Dehydrogenases or reductases are the enzymes involved. These enzymes are called oxidases when the oxygen atom is the acceptor. Enzymes bind both reactant molecules (called the substrate), tightly and specifically, at a site on the enzyme molecule called the active site (Figurebelow). By binding reactants at the active site, enzymes also position reactants correctly, so they do not have to overcome intermolecular forces that would otherwise push them apart.Biology.
