None of the above

Detailed explanation-1: -All enzymes have an ideal pH value, which is called optimal pH. Under the optimum pH conditions, each enzyme showed the maximum activity. For example, the optimum pH of an enzyme that works in the acidic environment of the human stomach is lower than that of an enzyme that works in a neutral environment of human blood.
Detailed explanation-2: -pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. Extreme pH values can cause enzymes to denature.
Detailed explanation-3: -When an enzyme denatures, its active site changes its shape, as you can see in this diagram. This is because the protein structure of the enzyme has changed. You might notice that the active site is no longer a complementary shape to a specific substrate molecule.
Detailed explanation-4: -Changing the pH will affect the charges on the amino acid molecules. Amino acids that attracted each other may no longer be. Again, the shape of the enzyme, along with its active site, will change. Extremes of pH also denature enzymes.
