Wood is extremely flammable, so why don't trees spontaneously burst into flame? d. Enzymes increase the enthalpy of the reactant molecules. b. Enzymes are generally proteins. d. Catalyst lower the activation energy of a chemical reaction. ATP acts as an allosteric inhibitor of many enzymes in catabolic pathways while ADP acts as an allosteric activator of many enzymes in catabolic pathways, A series of enzymes catalyzes the series of reactions shown below. Which statement is true of enzyme catalysts? the enzyme undergoes a conformational change that brings substrates closer (C) They are act. 2) adenyl-luciferin + O2 -> oxyluciferin +H2O + CO2 + AMP + light b. Enzymes work generally on a broad range of substrates. the substrate binds to enzyme with low specificity.b. b. The reason for this is B. heating damages the enzyme in liver that breaks down hydrogen peroxide. Enzymes catalyze only a particular reaction of specific substrates. True or False: Allosteric enzyme are enzymes that can be turned on and off. a. add more of the enzyme. Which curve(s) on the graphs may represent the temperature and pH profiles of an enzyme taken from a bacterium that lives in a mildly alkaline hot springs at temperatures of 70C or higher? When hydrogen and oxygen combine to form water, water is Identify the reactant(s) in the chemical reaction, CO2 + H2O = H2CO3. c. N-acetylcysteine They are usually highly spontaneous chemical reactions. the ATP levels in the cell are high and the ADP levels are low. Which of the following statements about substrate molecules in their transition state is FALSE? b. A. enzymes are consumed during chemical reactions B. Enzymes decrease the free energy of activation of specific reactions C. Enzymes in. c. by changing the free energy of the reactants They are specific for a particular chemi, Which of the following options is correct? e. the optimal activity of an enzyme occurs over a narrow temperature range. reports frequency, urgency, and nocturia 4\times 44; he has a weak stream and has to sit to void. a. Enzymes lower the free energy change of the reaction. c) Enzymes are denatured by a reaction to catalyze it. After correcting for the dilution, the results are as follows: 1:2 = 3000 1:4 = 3600 Dilutions are made a second time and assayed again but give identical results. B. decrease the amount of energy required for a reaction. C. Since 1880, the 10 hottest years on record have been in the past 17 years. What role does malonic acid play in this reaction? c. Both a and b are correct. The binding of the first two molecules must cause a 3-dimensional change that opens another active site on the enzyme. b. d. None of these answers are correct. They are made of amino acid, Which of the following statements about enzymes is true? What are some examples of how providers can receive incentives? Which of the following is true of enzymes and substrates. d. Burning wood is an endergonic reaction that requires energy from fire to drive it. a. Enzymes increase the energy of the reactant molecules. B) They speed up the rate of chemical reactions. a. Lactase can function equally effectively at many different pH levels b. C. fatty acids (c) Endergonic reactions have an energy of activation. Many are located on the plasma membrane as integral membrane proteins or peripheral membrane proteins.
