Which of the statement is true regarding Km?

Options

  1. AIt is the measure of the stability of the ES complex
  2. BIt is the measure of the stability of the affinity of an enzyme for its substrate
  3. CA high Km indicates weak substrate binding
  4. DAll of these

Correct answer

D. All of these

Step-by-step solution

Michaelis and Menten (1913) introduced a constant Km (Michaelis constant). It is a mathematical derivative or constant which indicates the substrate concentration at which the chemical reaction catalyzed by an enzyme attains half its maximum velocity (Vmax). Km indicates the affinity of the enzyme for its substrate.
