Assertion : Activity of an enzyme is pH\mathrm{pH} dependent. Reason : Change in pH\mathrm{pH} affects the solubility of the enzyme in water.

Options

  1. AIf both assertion and reason are true and the reason is the correct explanation of the assertion
  2. BIf both assertion and reason are true and the reason is not the correct explanation of the assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

B. If both assertion and reason are true and the reason is not the correct explanation of the assertion

Step-by-step solution

Enzymes are proteins which act as catalyst for bio-chemical reactions. pH\mathrm{pH} affect their activity as protonation-deprotonation may cause denaturation of the protein structure. Solubility is also affected.
