Q1:

A noncompetitive inhibitor of an enzyme-catalyzed reaction

A increases KM and increases Vmax

B increases KM and reduces Vmax

C reduces KM and increases Vmax

D reduces KM and reduces Vmax

ANS:B - increases KM and reduces Vmax

As the Vmax decreasing the rate of reaction will be faster resulting in increased km.
