In non-competitive enzyme action:: (A) Vmaxis increased, (B) Apparent km is increased, (C) Apparent km is unchanged, (D) Concentration of active enzyme moleculeis reduced.
Answer is C. Ans. C. Apparent km is unchangedNon-Competitive inhibition- The inhibitor and the substrate binds at different sites on the enzyme. It can bind either free enzyme or the ES complex, thereby preventing the reaction from occurring.In this inhibition Km value is Unchanged and Vmax decreases.
