  • question_answer
    Assertion : Haemoglobin is said to be a conjugated protein. Reason : It is composed of a protein called haem and a non-protein iron porphyrin complex called globin.

    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: C

    Solution :

    Conjugated proteins are the proteins which are formed by the binding of a simple protein with a non-protein prosthetic group. Conjugated chromoproteins are the pigment protein complexes. Hemoglobin is one such conjugated chromoprotein. It is composed of a simple protein called ?globin? and non protein iron\[(F{{e}^{2+}})\]porphyrin complex called ?heme?. 100 ml of blood contains about 15g of hemoglobin. Four\[F{{e}^{2+}}\]ions of heme can loosely bound to upto four molecules of oxygen, thus enabling hemoglobin to carry oxygen.
