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...

HI HCI reactants Reaction intermediates are species that are formed in one step of a mechanism and consumed in another step. For example, can act as an intermediate in the following reaction: H2(g) + 2Cl(g) + 2HCl(g) + 12(g). You can often express the concentration of in terms of the concentrations of the of the overall reaction to be consistent with the experimentally observed rate law as the overall reaction...

6) Whale insulin could be distinguished seralogically from pig insulin in spite of identical primary sequence. This is because: A) They were folded at different temperatures in the different species. B) They were folded using different chaperone proteins. C) They were folded as larger precursor proteins with differing primary structure D) The antibodies used were made from denatured insulin 7) Enzymes are potent catalysts because they A) increase the equilibrium constants for the reactions they catalyze B) lower the activation...
