Many biosynthetic pathways are regulated by feedback inhibition of enzymes. In a particular type of feedback inhibition, two endproducts individually do not inhibit an enzyme upstream in the pathway at all, but when both are present they inhibit the same enzyme significantly. What type of feedback inhibition do these inhibitors represent?

For the hypothetical reversible reaction where S is converted to P, the rate constant for the forward reaction is 105 s-1 while that of the backward reaction is 101 s-1. If the reaction is catalyzed by an enzyme, the rate constant for the forward reaction increases 100-fold. What will be the equilibrium constant of the enzyme catalyzed reaction?

Consider an enzyme catalysed reaction treated with inhibitor. Enzyme kinetic was analysed with Eadie Hofstee equation. A plot of V0 versus V0/[S] for an enzyme-catalyzed reaction is shown below. The control curve was obtained in the absence of inhibitor. Which effect is shown on the enzyme activity when an inhibitor is added to the reaction mixture?
