Question

Choose the correct answer from the alternatives given:
An example of conjugated protein is

• A. Albumin
• B. Haemoglobin
• C. Phosphoprotein
• D. Myoglobin

Answer 1

The correct option is C Phosphoprotein

• A conjugated protein is a protein that functions in the interaction with other non-polypeptide chemical groups attached by covalent bonding or weak interactions. Examples: lipoproteins (lipids attached with proteins), glycoproteins (oligosaccharides with proteins), phosphoproteins (phosphate group attached with proteins), metalloproteins (metal ions attached with proteins), etc.
  
• Albumin is the protein made by the liver. It carries various substances throughout the body, including hormones, vitamins and enzymes.
  
• Haemoglobin is the blood protein responsible for transporting oxygen in the blood of vertebrates. Its molecule comprises four subunits each containing an iron atom attached to the harem group.
  
• Myoglobin is an iron and oxygen-binding protein found in muscle tissues of the vertebrates.
  

Hence, the correct answer is 'Phosphoprotein'.
