Rate Law

Q. The enzyme Y catalyzes the elementary reaction AB → B An enzyme concentration of 0.5 uM AB to the products A and B per second. Note: Since the concentrations of species in the cytoplasm of cells is small, the concentration unit of micromolar (uM or 10^-6 M) is used for consistency with biochemical systems. What will happen when each of the following is added to a solution that contains 1.0 uM Y and 0.8 uM AB? Drag each item into the appropriate bin.
