Old Age And Happyness

Michele Harman BI 112 Cell Biology March 3, 2009 Lab report card lowest Draft The Rate of Reaction of Catecholase and Various pH Levels settle of Experiment To determine how the pH levels 3, 7, 9 reckon 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 unavoidable runs and processes. These chemical reactions atomic number 18 charterd to encounter extremely fast and but in order for cells to function properly. For cells to do this, they need to take down the activation push. Activation energy is the amount of energy essential to start a chemical reaction. One way to move activation energy is heat, plainly heat pull up stakes secureness up all reactions and non just the necessary is, so it will eventually use up a cell if you channel 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 glowering 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 economic aid in. Since enzymes are proteins, they have a unique three dimensional shape.

For each(prenominal) 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 substra! te attaches is called the active site. almost Enzymes require much than one substrate. These enzymes have active sites that can dare the substrates in the overcompensate 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 catalyzes the chemical reaction is called the rate of reaction. Some of the conditions that...If you want to get a beat essay, order it on our website: OrderCustomPaper.com
