Below are the Km,Vmax,kcat, and kcat/Km values showing the effect of different substrates on the activity of tropinone reductase. Based on these values, tropinone reductase has the greatest affinity for which substrate? 3-quinuclidinone hydrochloride 4-methylcyclohexanone Tropinone Tropine Enzyme feathertopase binds its substrate with a Km of 4M and a Vmax of 20Mmin1. With the addition of 20mM of an inhibitor the apparent Km of 6M and an apparent Vmax of 10Mmin1. Based on this, which of the following is true? a=2 and a=3 a=3 and a=2 a=3 a=2 and a=1.5 a=1.5
