A) exergonic; spontaneous B) exergonic; endergonic C) free energy; entropy D) work; energy E) entropy; enthalpy 2) If an enzyme has been inhibited noncompetitively, A) the Δ G for the reaction it catalyzes will always be negative. B) the active site will be occupied by the inhibitor molecule. C) raising substrate concentration will increase inhibition. D) more energy will be necessary to initiate the reaction. E) the inhibitor molecule may be chemically unrelated to the substrate 3) Which of the following characteristics is not associated with allosteric regulation of an enzyme's activity? 4) In this branched metabolic pathway, a red arrow with a minus sign symbolizes inhibition of a metabolic step by an end product: Which reaction would prevail if both Q and S were present in the cell in high concentrations?

Problem Set 3 BILD1 / Spring 2010 Chapters 8-10 Dr. Kiger 2 5) What is the correct label for "A"? 6) Which of the following reactions would be endergonic? 7) The binding of an allosteric inhibitor to an enzyme causes the rate of product formation by the enzyme to decrease. Which of the following best explains why this decrease occurs? A) The allosteric inhibitor binds to the active site, preventing the substrate from binding. B) The allosteric inhibitor causes free energy change of the reaction to increase. C) The allosteric inhibitor causes a structural change in the enzyme that prevents the substrate from binding at the active site. D) The allosteric inhibitor lowers the temperature of the active site. E) The allosteric inhibitor binds to the substrate and prevents it from binding at the active site.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
