NEET Biology Biomolecules / जैव-अणु Question Bank Assertion and Reason

  • question_answer
    Assertion : Enzyme substrate complex remains throughout the reaction. Reason : The greater the affinity of the enzyme for a substrate, the higher is the catalytic activity.

    A) If both the assertion and the reason are true and the reason is a correct explanation of the assertion

    B) If both the assertion and reason are true but the reason is not a correct explanation of the assertion 

    C) If the assertion is true but the reason is false

    D) If both the assertion and reason are false

    E) If the assertion is false but reason is true

    Correct Answer: E

    Solution :

      The enzymes substrate complex is short lived. The substrate is changed into products. The products remain complexed with the active site of the enzyme for a brief period. They soon separate and the active site is freed to perform another catalytic act. Enzymes activity depends upon the their affinity of substrates. If turnover number of substrate is higher, then enzymes show high affinity towards substrate. The number of substrate molecules changed per minute by a molecule or enzyme is called turn over number.
