Vedclass · Answer

(D) Enzymatic activity is highly sensitive to the presence of specific metal ions. Heavy metal ions,such as mercury $(Hg^{2+})$,lead $(Pb^{2+})$,and cadmium $(Cd^{2+})$,act as non-competitive inhibitors. They bind to the sulfhydryl $(-SH)$ groups of amino acid residues in the enzyme's active site or elsewhere,causing conformational changes that denature the enzyme or block the active site,thereby rendering the enzyme inactive and toxic to the biological system.
