Question

A storage protein is

• A. Keratin
• B. Collagen
• C. Haemoglobin
• D. Glutelin/Globulin

Answer 1

Answer: (D)

Glutelin/Globulin

Globular proteins are spherical in shape. It is characterized by twisted and folded amino acid chain to increase the protein's solubility in water by placing polar groups of atoms at the protein's surface. The polar groups can interact with the neighboring water molecules which further increase the water solubility.

Globulin is the protein which is produced by the immune system and helps in the defensive mechanism. It acts as a protein storage within seeds. Keratin and collagen is a structural protein. Hemoglobin helps in transfer of oxygen through the blood.

So, the correct answer is option D.
