Regarding enzyme activity, reversible loss of catalytic efficiency is most commonly associated with

A. Low temperature exposure

✓

B. Very high temperature exposure

C. Extreme acidic conditions causing denaturation

D. Hydrolysis of peptide bonds

📝 Explanation

Low temperatures slow molecular motion without permanently altering enzyme structure. Normal activity usually returns when the temperature is restored to the optimum value.
