Enzymes are important molecules in biochemistry that catalyze reactions. The energy diagram illustrates the difference between a catalyzed reaction and an uncatalyzed reaction. Label the energy diagram. Answer Bank free energy catalyzed reaction AG for reaction transition state reaction progress activation energy uncatalyzed reaction products reactants (substrate) What ways do enzymatic catalysts increase the rates of reactions? They increase the concentration of reactants. They promote the formation of a transition state. They decrease the free energy of the reaction. They lower the activation energy of the reaction. They shift the reaction equilibrium toward the products.
