12. Which of the following statements is true of enzyme catalysts? A B C To be effective, they must be present at the same concentration as their substrate. They can increase the equilibrium constant for a given reaction by a thousand-fold or more. They lower the activation energy for conversion of substrate to product. Their catalytic activity is independent of pH. They are generally equally active on D and L isomers of a given substrate. D E 13. In competitive...
