Explanation

Extreme changes in pH can disrupt the enzyme's three-dimensional structure, leading to denaturation. While pH shifts may also affect ionization of amino acids at the active site or the substrate, the primary consequence of a severe pH change is enzyme denaturation, which impairs its function.
