    Which one of the following is a conjugated protein?

    A)  Phosphoprotein

    B)  Glycoprotein

    C)  Chromoprotein

    D)  All of the above

    Correct Answer: D

    Solution :

    Conjugated proteins on hydrolysis give a non-protein portion along with a-ammo acid. The non-protein portion is called prosthetic group.
    Protein Prosthetic group
    Phosphoprotein Lipid (e.g., lecithin)
    Glycoprotein Sugar
    Chromoprotein Colouring matter such as red coloured protophyrin
    Since, all of them have non-protein part hence, all of them are conjugated protein.
