Graphs I-IV depict the effect of pH on the activity of four different hydrolytic enzymes. Enzymes with their highest activity at an alkaline(basic) pH are represented by which of the graphs?

• I only

• II only

• III only

• I and IV

Graphs I-IV depict the effect of pH on the activity of four different hydrolytic enzymes. Graphs representing enzymes sensitive to changes in pH include which of the following?

• I only

• IV only

• I and III only

• I, II, and III

Graphs I-IV depict the effect of pH on the activity of four different hydrolytic enzymes. The most likely explanation for the results shown in Graph I is that

• pH affects the shape of the active site of the enzyme.

• pH affects the temperature of the reaction.

• the enzyme has a quaternary structure.

• pH affects the primary structure of the enzyme.

Graphs I-IV depict the effect of pH on the activity of four different hydrolytic enzymes. Which of the graphs would be most likely to represent an enzyme active in the human stomach?

• I

• II

• III

• IV
