If an enzyme reaction follows the Michaelis Menten kinetics represented by the equation:

${\mathrm{V}}_0={\mathrm{V}}_{\max }\frac{\left[\mathrm{S}\right]}{{\mathrm{K}}_{\mathrm{M}}+\left[\mathrm{S}\right]}$

Where ${\mathrm{V}}_0$ is the initial reaction velocity, ${\mathrm{V}}_{\max }$ is the maximal reaction velocity,  ${\mathrm{K}}_{\mathrm{M}}$ is the Michaelis constant, and [S] is the substrate concentration. Which of the following statements is correct?

The graph below depicts the velocity of an enzyme-catalyzed reaction vs. substrate concentration. Identify the alphabets with the correct descriptions.

I. $\mathrm{A}=$ Enzyme activity

II. $\mathrm{B}=$ Substrate concentration at maximum velocity

III. $\mathrm{A}=$ Substrate concentration at which half of the maximum velocity

IV. $\mathrm{B}=$ Half of the maximum velocity
