Redox (short for reductionâoxidation reaction) is a chemical reaction in which the oxidation states of atoms are changed. Any such reaction involves both a reduction process and a complementary oxidation process, two key concepts involved with electron transfer processes.
(See Table 1 for a partial list of enzymes that require NAD + and NADP + .) The redox reaction shown in Figure 2 is catalyzed by the oxidoreductase enzyme alcohol dehydrogenase. In this reaction, two hydrogen atoms and two electrons (the two electrons of the C-H bond) are removed from the ethanol molecule.
