Legge Practice Exam BCHS 3304 Fall 2005 Note: This homework will not be collected. However, quizzes and exams will assume that you have completed and understand the homework assignment and could answer related questions. In this homework you are also given a practice exam II, which you may use as a study tool. 1). An enzyme catalyzes a reaction without itself being __________ in the process. It does this by __________ of the reaction. Enzymes preferentially bind the ____________ in an ideal situation. The extent to which an enzyme will catalyze a reaction is ultimately dictated by the ___________ for the reaction. : An enzyme catalyzes a reaction without itself being consumed/altered in the process. It does this by lowering the activation energy of the reaction. Enzymes preferentially bind the transition state in an ideal situation. The extent to which an enzyme will catalyze a reaction is ultimately dictated by the equilibrium constant for the reaction. 2). What happens if you add more enzyme to an enzyme-catalyzed reaction already operating at V max ? a). K M will decrease. b). No change. c). Observed rate will be faster. d). k cat will increase. e). Observed rate will be slower. : (c), the observed rate of reaction will be faster. 3). The basis for enzyme-substrate specificity is: a). shape/geometry. b). Keq. c). stereospecificity. d). electronic complementarity. e). none of the above. f). a, d, and c. g). all of the above. : (f), Shape/geometry, electronic complementarity, and stereospecificity are the basis for enzyme-substrate specificity.

4). Given the following equation: E + S  ES E + P k 1 = the rate of formation of the Michaelis Complex. k -1 = the rate at which the Michaelis Complex falls apart to E + S. k 2 = the rate at which the Michaelis Complex forms E + P. When [E T ] = [ES], which of the following expressions defines the V max ? a). V
