Practice: True or false: Increasing [S] in the presence of an uncompetitive inhibitor will lower the inhibition constant (KI).

Practice: In the presence of an uncompetitive inhibitor that binds __________ the substrate, the apparent Vmax ____________ and the apparent Km ____________ with respect to the Vmax and Km of the uninhibited enzyme.
