Assertion : Activity of an enzyme is pH dependent. Reason : Change in pH affects the solubility of the enzyme in water.
Options
- AIf both assertion and reason are true and the reason is the correct explanation of the assertion
- BIf both assertion and reason are true and the reason is not the correct explanation of the assertion
- CIf assertion is true but reason is false
- 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 affect their activity as protonation-deprotonation may cause denaturation of the protein structure. Solubility is also affected.
