Is energy released or consumed by this reaction? If an enzyme, which catalyzes this reaction is added, what will happen to delta (G) If this reaction is coupled to another reaction, whose delta(G) is -12 kcal/mol, what will be the net delta(G) value? will the overall reaction be spontaneous
An enzyme has a single active site at which it can bind and hydrolyze either X or Y; however, the enzyme cannot bind X and Y at the same time. Answer the following questions regarding the Km and Vmax of this enzyme. (a) Will the Km for X be affected if Y is present in the reaction mixture? Explain. (b) Will Vmax for X be affected if Y is present in the reaction mixture? Explain. (a) No, X competes with Y for binding, so the apparent Km for X will stay the same. (b) Yes, the Vmax for X will decrease in the presence of Y. (a) No, Y does not compete with X for binding, so the apparent Km for X will stay the same. (b) No, the Vmax for X will be unaffected by the presence of Y.
