Enzymes increase the reaction rate by lowering the activation energy: This statement is correct. Enzymes lower the activation energy required for a reaction to occur, which increases the reaction rate. Show more…

Which of the following is NOT true about enzymes? Nucleophilic groups can catalyze reactions through the transient formation of covalent bonds with the substrate. Enzyme inhibitors interact reversibly or irreversibly with an enzyme to alter its Km and/or Vmax values. Transition state stabilization can significantly increase the activation energy for a reaction. Enzymes typically act under milder conditions of temperature and pH than non-enzyme chemical catalysts. Zymogens are the inactive precursors of enzyme.

Which of these statements about enzyme-catalyzed reactions is FALSE? An enzyme is a catalyst for speeding up both substrate-to-product and product-to-substrate reactions. A competitive inhibitor changes the Michaelis-Menten constant and maximal velocity of the enzyme-catalyzed reaction. An uncompetitive inhibitor changes the Michaelis-Menten constant and maximal velocity of the enzyme-catalyzed reaction. A non-competitive inhibitor changes the maximal velocity of the enzyme-catalyzed reaction. The Michaelis-Menten constant is the substrate concentration at which the enzyme-catalyzed reaction attains half-maximal velocity.

Which of the following statements about enzymes is false? A. An enzyme catalyzes a chemical reaction by amplifying the energy of activation. B. The presence of activators or inhibitors can alter the rate at which an enzyme catalyzes a reaction. C. The shape of the enzyme creates an active site that binds to one or more specific substrates. D. Enzymes are proteins. E. Without enzymes, many biochemical reactions would not occur fast enough to support life.
