Which of the following is NOT correct regarding the relationships between [S],K_m,and V_mₐₓ? A)As the [S] is increased,v approaches the limiting value,Vmax. B)K_m = V_max/2. C)The rate of the reaction,v,follows a first-order rate equation: v = K'[A] and K' = V_max/K_m. D)The rate of product formed,v,is at V_max when [S] >> K_m.

K_m and V_max/2 are not interchangeable. K_m represents the substrate concentration at which the reaction rate is half of its maximum value, while V_max represents the maximum velocity that can be achieved at saturating substrate concentrations.
