What are the final concentrations of sand p

The conversion of molecule S to productP has a Keq = 0.75. Two different, but relatedenzymes, A and B, can catalyzethe reaction. The product P serves as anallosteric inhibitor of enzyme B, but not ofenzyme A.

A. 10 mMS is placed into three separate test tubes (Tubes 12, 2,and 3) containing, respectively, no enzyme, enzymeA, and enzyme B. Describe theendpoint of the reaction in each tube, and tell why that is theendpoint. What are the final concentrations of Sand P (show your calculations)?

B. Which tube(uncatalyzed, enzyme A, or enzymeB) will get to the endpoint first, second andthird? Explain.

C. Describe the endpoint of this reaction if the enzymesA and B were found in a cell.
