Suppose that an enzyme has the capacity to convert 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 reaction 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?
