AP BIOLOGY

Detailed explanation-1: -Each enzyme work bests at a specific pH value. The optimum pH for an enzyme depends on where it normally works. For example, enzymes in the small intestine have an optimum pH of about 7.5, but stomach enzymes have an optimum pH of about 2.

Detailed explanation-2: -Enzyme activity is affected by several things and each type of enzyme has its own specific optimum conditions under which it works best.

Detailed explanation-3: -Each enzyme has an ideal temperature and pH: pH: Enzymes are sensitive to acidity and alkalinity. They don’t work properly if an environment is too acidic or basic. For example, an enzyme in the stomach called pepsin breaks down proteins.

Detailed explanation-4: -Although some enzymes exhibit activity in a broad range of pH [1–3], many show maximal activity at a narrow pH range [4–6], referred to as the pH optimum.
