<prompt> Effect of Vmax and Km in competitive inhibition is as followsKm unchangedVmax increased, Km unchangedKm increased, V max unchangedKm and Vmax increased  <response>: In competitive inhibition, Drug binds to enzyme only .So, Velocity remains unchanged and Conc- km increases. In non- competitive inhibition, drug binds to enzyme substrate complex deceasing velocity unaffecting km. Ref: K.D.Tripati.7th ed. Pg 39
