2.   Each of the five enzymes listed below specifically catalyzes the reaction shown.
      Considering the classification scheme for types of enzymes given in the Pattern
      Recognition section, decide to which group each of the enzymes belongs:

      

3.   What would happen to the rate of an enzyme catalyzed reaction if the
      concentration of the enzyme is doubled? What would happen to the rate if the
      concentration of the substrate is doubled? Explain your answers on the basis
      of kinetics (see Reaction Rates module).
4.   The activity of a certain bacterial enzyme at various temperatures
      is shown in the following graph:

                    
     Suppose a person is infected with this bacterium.

         a.   What happens to the activity of this enzyme if the person has a
               high fever? [It increases (approaching 50 °C optimum).]
         b.   What happens to the activity of this enzyme if the person’s
               temperature drops below 37 °C? [It decreases.]
         c.   At what temperature does this enzyme have its maximum
               activity? [50 °C.]
