Enzymes are proteins that every living cell produces to catalyze a specific chemical reaction. Without enzymes, the same chemical reaction would take much longer to occur, and would not be able to support life as we know. For that reason, a chemical reaction first needs to overcome an activation energy E_a, which is difficult. Therefore, cells produce enzymes that lowers the activation energy E_a Enzymes are shape-specific; they will only bind with specific reactants, also called substrates. Substrates
for Enzyme Activity of Catechol Oxidase. Tiffany Connors, 2015. Functional Biology. Texas State University, San Marcos, TX 78666. Cofactors support enzymes in catalyzing reactions. By removing cofactors through the addition of chelators, the effect of cofactors on enzyme activity of potato catechol oxidase can be observed. This makes it possible to determine to what extent cofactors aid catechol oxidase in the oxidation of o-diphenols to o-quinones. For this experiment, four assays of catechol oxidase
Effects of NaCl on Catechol Oxidase Activity A Catechol Oxidase is an enzyme and enzymes are proteins which are also catalysts, meaning they affect the rate of chemical reactions.(http://sciencelearningcenter.pbworks.com/f/3-Enzymes.pdf). This lab was constructed to observe the relationship of an environmental parameter, for this experiment the effects of NaCl on Catechol Oxidase Activity. Salt concentrations that are close to zero; the enzyme molecules of charged amino acid side chains will attract
1. Introduction: Enzymes are large protein molecules that are made up of amino acids monomers linked together by peptide bonds. Enzymes are essential in controlling and regulating the metabolism, they are biological catalysts. These biological catalysts are important in biochemical reactions by speeding these reactions that are basically slow (or that cannot happen in the absence of these catalysts), these catalysts speed up a reaction by lowering its activation energy. Enzymes are not consumed or
