All of the following are true of enzyme-catalyzed reactions EXCEPT:A.the presence or absence of a post-translational modification may alter the activation energy Ea of the reaction.B.the enzyme does not affect the net reaction rate if the ratio of products to reactants equals Keq for the reaction.C.substrates can covalently modify the enzyme to cause a permanent decrease in the enzyme's turnover number kcat.D.the saturation of enzyme active sites by substrate molecules limits the maximum reaction velocity Vmax.Submit

Which of the following correctly describes how enzymes lower the activation energy of a biochemical reaction?Question 8Answera.Enzymes increase the temperature of the reaction, providing more energy to the reactants.b.Enzymes stabilize the transition state, reducing the energy required to reach it.c.Enzymes alter the equilibrium constant of the reaction, favoring product formation.d.Enzymes are consumed in the reaction and must be continually replaced.
