Old Age And Happyness

Michele Harman BI 112 Cell Biology March 3, 2009 Lab make known lowest Draft The Rate of Reaction of Catecholase and Various pH Levels settle of Experiment To determine how the pH levels 3, 7, 9 happen upon the rate of reply of the enzyme catecholase and its substrate catechol. Introduction The cells of living organisms argon constantly performing thousands of chemic substance receptions to complete needful runs and processes. These chemical reactions ar charterd to encounter extremely fast and merely in order for cells to function properly. For cells to do this, they need to land the activation push. Activation energy is the amount of energy needed to start a chemical reaction. One way to disdain activation energy is heat, plainly heat ordain step on it up all reactions and non just the necessary one(a)s, so it will eventually use up a cell if you take too much. The solution to the business is enzymes. Enzymes are proteins that act as catalysts. Catalysts are molecules that speed up chemical reactions by take down activation energy. They are not consumed during the chemical reactions. There are thousands of unalike types of enzymes that have different shapes and specific chemical reactions that they support in. Since enzymes are proteins, they have a unique three dimensional shape. For individually enzyme, there is a specific reactant that suit of clothess the enzyme to catalyze the chemical reaction. This reactant is called a substrate. On each enzyme there is a specific space where the substrate attaches. The stadium on the enzyme on which the substrate attaches is called the active site. about Enzymes require much than one substrate. These enzymes have active sites that can dare the substrates in the remedy order so the chemical reaction can occur. For each enzyme, there are optimal conditions that cause the enzyme to catalyze reactions more efficiently. (1.) The efficiency in which the enzyme cat alyzes the chemical reaction is called the r! ate of reaction. Some of the conditions that...If you want to get a beat essay, order it on our website: OrderCustomPaper.com
