Suppose that an enzyme has the capacity to conver substrate A (Km= 1 x 10^-3 M) to a product P1. Suppose the same enzyme can also convert another substrate B (Km = 1 x 10^-6 M) to a different product, P2. ALso suppose that an equal Vmax is possible with both of the substrates. Which substrate will show a greater rate of rection at 1 x 10^-3 M? Which substrate will show a greater rate at 1 x 10^-2 M? What will be the effect of addition of B on the rate of reaction with A?
