11. Which of the following statements about a plot of V0 vs. [S] for an enzyme that follows Michaelis- Menten kinetics is false?
(A) As [S] increases, the initial velocity of reaction V0 also increases.
(B) At very high [S], the velocity curve becomes a horizontal line that intersects the y-axis at Km.
(C) Km is the [S] at which V0 = 1/2 Vmax.
(D) The shape of the curve is a hyperbola.
(E) The y-axis is a rate term with units of µm/min.
