The graph given below shows the Michaelis-Menten kinetics for two reactions (R1 and R2; represented as solid and dotted lines, respectively). Enzymes E1 and E2 have V_ values, V_ 1 and V_ 2 , respectively. The respective K_M values for E 1 and E 2 are K _ M 1 and K _ M 2 . ( K _ M 1 = K _ M 2 ) . The correct statement(s) for reactions R1 and R2 is/are

Options

  1. AE₁ and E₂ can never be the same enzyme.
  2. BE₁ and E₂ may be the same enzyme, acting on two different substrates with different affinities.
  3. CE₁ and E₂ may represent two different concentrations of the same enzyme, acting on the same substrate.
  4. DE₁ and E₂ may be two different enzymes, with the same affinity for the substrate.

Correct answer

D. E₁ and E₂ may be two different enzymes, with the same affinity for the substrate.
