Introduction:
Enzymes are biological molecules that act as a catalyst to significantly speed up the rate of the chemical reactions that take place within cells without being used up in the process. According to the website, www.ducksters.com, “enzymes are special types of proteins. Like all proteins, enzymes are made from strings of amino acids. The function of the enzyme is determined by the sequence of amino acids, types of amino acids, and the shape of the string.” Along with this we need to know about a peroxidase; “A peroxidase is one of a number of enzymes that act as catalysts to allow a variety of biological processes to take place. Specifically, they promote the oxidation of various compounds using naturally occurring peroxides, especially hydrogen peroxide (H2O2), which are reduced, forming water. Peroxides are created as byproducts of various biochemical reactions within organisms, but can cause damage as they are oxidizing agents. Peroxidases break these compounds down in to harmless substances by adding hydrogen, obtained from another molecule — known as a donor molecule — in a reduction-oxidation (redox) reaction in which the peroxide is reduced to form water, and the other molecule is oxidized. There are a large number of these enzymes, and they are found in plants and animals, including humans.”, according to an article written on What is a peroxidase? From www.wisegeek.org. Isozymes also known as isoenzymes are according to an article, Isozymes Provide a…
