- FoF1 ATPase is the enzyme that catalyzes ATP synthesis. The enzyme itself is deactivated by ATP. What mode of enzyme regulation is being exemplified? Select the correct response: Trasncriptional control Covalent modification Proteolytic modification Allosteric regulation Compartmentationarrow_forwardAs you change the temperature from a low temperature to a high temperature what happens to the rate of an enzymatic reaction, in general terms? A The reaction rate will steadily increase as the temperature increases. B The reaction rate will steadily decrease as the temperature increases. C The reaction rate will start low, then increase, and then decrease again as the temperature increases. D The reaction rate will not change as the temperature increases.arrow_forwardFill in the diagram on the next page: Write the name of the enzyme in the ovals, Draw the metabolite that goes in the large rectangular boxes.

- Enzyme 3 (diagram) is involved in negative feedback inhibition. It binds ATP at an inhibitory allosteric enzyme site on phosphofructokinase. What reagents does phosphofructokinase take into its active site. What are the products of the reaction that phosphofructokinase mediates. What do you think the ΔG (free energy) of this reaction is positive or negative, endothermic vs exothermic? Explain your answer above ATP is the end-product of ETC (electron transport chain), and at high concentrations of ATP, phosphofructokinase is inhibited allosterically. Please note that ATP is required in the active site.

- Which of the following is a primary function of the active site of an enzyme? a. It binds allosteric regulators of the enzyme. b. It binds noncompetitive inhibitors of the enzyme. c. It catalyzes the reaction associated with the enzyme. d. It is activated by the presence of the end product of the metabolic pathway in which the enzyme is involved.

SHOW MORE The Km for X will be affected if Y is present in the reaction mixture. a Y is a competitive inhibitor of X. The Km for X will increase. d The Vmax for X will be affected if Y is present in the reaction mixture. pH dependence of Vmax reflects the ionization state of catalytic site residues. e Consider the following: X and Y are methanol (poisonous) and ethanol respectively. If the Km for X= 0.01 M and the Km f for Y = 0.001 M then 0.01 M Y is 10 times the concentration of Y required for 0.5 Vmax.
