Answer TRUE or FALSE.a. According to the lock-and-key model of enzyme action, the active site of an enzyme is not flexible in shape.b. In an enzyme-catalyzed reaction, the compound that does not undergo a chemical change is called the substrate.c. The nonprotein portion of a conjugated enzyme is not the enzyme’s active sited. Simple enzymes are composed only of protein; conjugated enzymes have nonprotein cofactors.
Question: A. To explore the consequences of coupling ATP hydrolysis under physiological conditions to a thermodynamically unfavorable biochemical reaction, consider the hypothetical transformation X⟶Y, for which Δ?′°=20.0 kJ/mol. What is the ratio of [Y]/[X][Y]/[X] at equilibrium? B. Suppose XX and YY participate in a sequence of reactions during which ATP is hydrolyzed to ADP and Pi. The overall reaction is X+ATP+H2O⟶Y+ADP+Pi Calculate [Y]/[X] for this reaction at equilibrium. Assume that the temperature is 25.0 °C and the equilibrium concentrations of ATP, ADP, and Pi are 1.00 M each. C. We know that [ATP], [ADP], and [Pi] are not 1.00 M under physiological conditions. Calculate [Y]/[X] for the ATP‑coupled reaction when the values of [ATP], [ADP], and [Pi] are those found in rat myocytes. Metabolite Concentration in rat myocytes (M) ATP 8.05x10-3 ADP 0.93x10-3 Pi 8.05x10-3
Question:- The enzyme aromatase is found in the cytoplasm of some cells and converts testosterone to estrogen. You decide to test aromatase from a particular cell, and oops, your lab partner admits he drastically increased the pH in all the test tubes. Which of the following is a likely result? a. The enzyme will be denatured and the substrate will not bind to the active site. b. The enzyme will convert testosterone to estrogen at a faster rate. c. The mistake will have no effect on the experiment, because enzymes are not sensitive to pH. d. The free energy will be lowered and the reaction will not proceed spontaneously.
