Question

Examlex · Accepted Answer

The Answer is A.When [S] is substituted for K_m in the equation, it becomes clear that [E] = [ES].Thus, half of the enzyme molecules are free and half are bound to the substrate.
B.Yes.If half of the enzyme molecules are bound to the substrate, it makes intuitive sense that the reaction rate is half of the maximum possible rate, or half of the rate observed when all of the enzyme molecules are bound to the substrate.
