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 …show more content…
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 Means of Regulation Specific to Distinct Tissues and Developmental Stages, written on www.ncbi.nlm.nih.gov, “enzymes that differ in amino acid sequence yet catalyze the same reaction.”. With this information we conducted this experiment, for the purpose of seeing what the difference would be in different parts of the plants. Based on this we came up with the question, are peroxidase isoenzymes different in roots and shoots of corn? According to the question the hypothesis for this experiment is that, peroxidase isoenzymes are different in roots and shoots of corn because even though they’re coming from the same plant different parts functions differently not requiring certain
