You are studying two reactions. The only difference in these reactions is that one has an enzyme and the other does not. Which of following statements must be false? A. The enzymatic reaction has less activation energy because it does not have a transition state. B. The activation energy of the reaction that lacks an enzyme is greater than the reaction that has an enzyme. C. The rate of reaction is greater in the enzymatic reaction. D. The delta G and the entropy of both of the reactions a...

False - correct answer True or False: an antagonist will behave in a similar manner to an endogenous substrate An antagonist blocks an endogenous substrate from binding to its receptor - correct answer How does an antagonist work? Bronchial Smooth Muscle Relaxation - correct answer Activation of B2-receptors in the lungs would produce what effect? Reduced Heart Rate and Contractility - correct answer Antagonism of B1-receptors in the heart would produce what effect? Enzymes catalyze ...

activation energy correct answers energy needed to get a reaction started Delta G (change in G - change in free energy) correct answers respresented in a reaction coordinate diagram. Positive is thermodynamically unfavorable. Negative is thermodynamically favorable (exergonic - release energy). = G(products) - G(reactants) enzyme correct answers catalyze chemical reaction. Lower activation energy. Biological catalyst (protein) enzyme inhibition correct answers results in decrease in act...

PATH 3610 – Midterm 1 The release of cytoplasmic enzymes from necrotic cells may be useful diagnostically. a. True b. False The cytoplasmic enzymes of necrotic cells may be released into the blood. This fact is useful diagnostically, as certain enzymes can be assayed in the serum using various tests. Bilirubin is: a. Lipid soluble when conjugated. b. Water soluble when conjugated. c. Conjugated in the kidney for excretion in the urine. Bilirubin is then bound to albumin and carried i...

A good transition-state analog: A) binds covalently to the enzyme. B) binds to the enzyme more tightly than the substrate. C) binds very weakly to the enzyme. D) is too unstable to isolate. E) must be almost identical to the substrate. - Answer-binds to the enzyme more tightly than the substrate. A major advance in the application of mass spectrometry to macromolecules came with the development of techniques to overcome which of the following problems? A) Macromolecules were insoluble i...
