A particular enzyme's activity is low at high pH but increases at lower pH. These data suggest that for efficient catalysis to occur, a functional group on the enzyme or on the substrate must be, protonated O reduced exidized Odenatured deprotonated

An plot of the activity of an allosteric enzyme (velocity (V) versus substrate concentration [S]) has a sigmoidal shape. How will the addition of an activator of this enzyme change its kinetic activity data? The curve will shift to the right The curve will shift to the left. The curve will become more sigmoidal, so that the first half is decreased and the second half increased The curve will be more hyperbolic There will be no effect Which of the following amino acids have side chains that fit into the S1 pocket of chymotrypsin? Phe Arg Asp Lys Ala
