Which type of bonds are mostly affected in an enzyme molecule when there are pH fluctuations?
Correct answer: A. Ionic bonds
- A. Ionic bonds
- B. Disulphide bonds
- C. Hydrogen bonds
- D. Peptide bonds
Explanation
Ionic bonds are most affected by changes in pH. These bonds are formed between oppositely charged ions. A change in pH can alter the charge on amino acid side chains, disrupting these bonds, which can lead to changes in enzyme structure and function.

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.
