The ATP hydrolysis reaction (shown below) has a AG of-31 kJ mol-'. NH2 NH2 Do you predict that AS is positive or negative for this reaction. Explain in one sentence. а. H20 -OCH2 OCH2 Energy Phosphate ion OH OH OH Adenosine triphosphate (ATP) Adenosine diphosphate (ADP) b. How does the hydrophobic effect contribute to the AS you predicted in part a. Make sure to discuss the ordering of water molecules in your answer. Include a minimum of 3 sentances in your explaination.

Question 23 An enzyme has a single active site at which it can bind and hydrolyze either X or Y but the enzyme cannot bind X and Y at the same time. Which of the following statements are TRUE? Multiple answers: Multiple answers are accepted for this question Select one or more answers and submit. For keyboard navigation... SHOW MORE V 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 V for X will be affected if Y is present in the reaction mixture. max pH dependence of Vmax reflects the ionization state of catalytic site e residues. Consider the following: X and Y are methanol (poisonous) and ethanol respectively. If the Km for X = 0.01 M and the Km for Y = 0.001 M then 0.01 M Y is 10 times the concentration of Y required for 0.5 Vmax. Addition of an enzyme to a chemical reaction increases the ratio of g products to reactants (Keg).

I need help with parts d-g  a.) For Ado: catalytic efficiency = 4.18 x 106 M-1s-1 For ATP: catalytic efficiency = 12.1 x 107 M-1s-1 b.) Both specificity constants are below the diffusion limit so neither substrate is limiting the reaction rate due to diffusion c.) Line weaver Burk equation for AdoK enzyme with Ado substrate: y = 0.68x + (2.04 x 104), where y = 1/vo and x = 1/[Ado]
