9. Which of the following statements about trypsin, chymotrypsin, and elastase are true? A. They are serine proteases. B. They are endopeptidases. C. Serine is part of both tetrahedral intermediates in the enzymatic mechanism. D. Acid, base, and nucleophilic catalysis are utilized in the overall mechanism for these proteases. E. All of the above are true. 10. Which of the following statements about enzyme-catalyzed isomerization of glucose-6- phosphate to fructose-6-phosphate is not true? A. The mechanism is totally different from the laboratory version of the enediol rearrangement. B. The first step is acid- and base-catalyzed ring opening. C. The second step is a base-catalyzed enediol rearrangement. D. The third step is acid- and base-catalyzed conversion of the enediol to a ketone. E. The fourth step is acid- and base-catalyzed ring closure.
