Which of these statements describes the pH optimum of an enzyme?
A)always between pH 6 and pH 8
B)nearly the same for all enzymes
C)pretty broad over 6 to 8 pH units
D)occurs when there is optimum secondary and tertiary structure in the active site of the enzyme

Question

Quizplus · Accepted Answer

The pH optimum of an enzyme is the pH at which its activity is maximized, and this occurs when the enzyme's secondary and tertiary structures are optimal, ensuring the active site is in the correct conformation for substrate binding and catalysis. The pH optimum varies widely among different enzymes, depending on their roles and the environments in which they function.
