Heavy metal ions that act as inhibitors (mercury, silver and copper) break_in enzymes.

Correct answer: B. Disulfide bridges

  • A. Peptide bonds
  • B. Disulfide bridges
  • C. Hydrogen bonds
  • D. Ionic bonds

Explanation

Heavy metal ions such as mercury, silver, and copper act as enzyme inhibitors by breaking disulfide bridges. These ions bind to the thiol (-SH) groups of cysteine residues, disrupting the covalent disulfide bonds that stabilize the enzyme's structure.

About Enzymes

Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
