According to the induced fit hypothesis of enzyme catalysis, which of the following is correct? - Enzymes lower the energy of activation for the reaction that they catalyze. Which of the following statements is (are) true about enzyme-catalyzed reactions? Altering the enzyme's activity. carbohydrates and protein, D. Antarctica lost about 36 cubic miles of ice between 2002 and 2005. The wrong pipet was used to make one of the dilutions It never involves coenzymes. a. the substrate binds to enzyme with low specificity. c. production of water from the sugar as bonds are broken between the sugar monomers Enzymes can only catalyze reactions in one direction. C. Enzymes operate most efficiently at optimum pH. c. Enzymes lower a reaction's activation energy. a. a) It is the amount of energy that must be produced by the reactants to end a chemical reaction. Enzymes increase the rate of chemical reaction by lowering activation energy barriers. Enzymes work best at a specified pH. a. slow down the rate at which organisms consume food. c. It blocks the binding of fumarate. a. d. None of these answers are correct. Enzymes do not alter the free or total energies of the reactant or product molecules. d.

B. decrease the amount of energy required for a reaction. Which of the following statements about enzyme-catalyzed reactions is true? Enzymes themselves change during each reaction and thus can only be used by the body a single time. b) an association stabilized by a covalent bond. 5. When hydrogen and oxygen combine to form water, water is Identify the reactant(s) in the chemical reaction, CO2 + H2O = H2CO3. d. heat the solution to 90C. Explain. the relative concentrations of A and B versus C and D. If ATP levels increase and ADP levels decrease c. They consume energy to build up polymers from monomers. c) one in which the enzyme is changed permanently. c. endothermic level the active site of the enzyme is where the chemical reaction takes place.d. All of these answers are correct. d. by changing the free energy change of the reaction. O Enzymes make reactions possible by changing the ground state of the reaction. 3. Enzymes are typically involved in coupled reactions. d.
