Which of the following statements about a plot of V0 vs. [S] for an enzyme that follows Michaelis-Menten kinetics is false?

#Unit 1. Molecules and their Interaction Relevant to Biology

  1. As [S] increases, the initial velocity of reaction V0 also increases.

  2. At very high [S], the velocity curve becomes a horizontal line that intersects the y-axis at Km.

  3. Km is the [S] at which V0 = 1/2 Vmax.

  4. The shape of the curve is a hyperbola.
