Plants represent one of the most basic examples of biological oxidation and reduction. When reduction-oxidation reactions occur simultaneously it is called a redox reaction or reduction-oxidation reaction. In the case of combustion, for example, the oxidation process is important in a sense that oxygen is needed to combine with other elements like carbon or hydrogen molecules in order for combustion to occur. Treatment of cholorophyll-a with acid removes the magnesium ion replacing it with two hydrogen atoms giving an olive-brown solid, phaeophytin-a. So, for microbes, passing electrons around between molecules — called oxidation and reduction — is important for gathering energy. Halliwell, Barry, and Okezie I. Aruoma. The most important reason transition metals are good catalysts is that they can lend electrons or withdraw electrons from the reagent, depending on the nature of the reaction. DRI plants need not be part of an integrated steel plant, as is characteristic of blast furnaces. For example, in a zinc electrode the standard oxidation potential is represented as. Most oxidation-reduction (redox) processes involve the transfer of oxygen atoms, hydrogen atoms, or electrons, with all three processes sharing two important characteristics: (1) they are coupled—i.e., in any oxidation reaction a reciprocal reduction occurs, and (2) they involve a characteristic net chemical change—i.e., an atom or electron goes from one unit of matter to another.
