Lab #1: Enzyme Kinetics Introduction Enzymes are organic catalysts, proteins that increase the rates of chemical reactions. The portion of a system's total energy that is available to do work is free energy. Chemical reactions involve transition states, whose free energy is higher than the total energy of either the reactants or the products. The difference between the free energy of the reactants and the free energy of the transition state is called the activation energy of the reaction. Enzymes reduce the activation energy of the reactions they catalyze. Because they are neither consumed nor modified in the chemical reactions they affect, small quantities of enzyme can mediate the formulation of large quantities of product. The three-dimensional structure of proteins (such as enzymes) can be altered by changes in temperature or pH. These changes in three-dimensional structure are calle...
