B. Kinetics of Simple and Enzyme-Catalyzed Reactions

Skills to Develop

  • write appropriate chemical and differential equations for the rate of disappearance of reactants or appearance of products for 1st order, pseudo first order, second order, reversible first order reactions
  • draw and interpret graphs for integrated rate equations (showing reactant or product concentrations as a function of time) and initial rate equations (showing the initial velocity vo as a function of reactant ;
  • derive kinetic rate constants from data and graphs of integrated rate and initial rate equations;
  • write appropriate chemical, differential equations, and initial rate equations for the rate of disappearance of reactants or appearance of products for simple enzyme catalyzed reaction;
  • differentiate between rapid and steady state assumptions;
  • simplify the initial rate equation containing rate constants for an enzyme catalyzed reactions to one replacing the rate constants with kcat and KM, and give operational and mathematical definitions of those constants;
