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
- AE₁ and E₂ can never be the same enzyme.
- BE₁ and E₂ may be the same enzyme, acting on two different substrates with different affinities.
- CE₁ and E₂ may represent two different concentrations of the same enzyme, acting on the same substrate.
- 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.
