Question

Oxygen in our blood is transported by a Protein, named:

• A. Keratin
• B. Collagen
• C. Haemoglobin
• D. Myoglobin

Answer 1

The correct option is C Haemoglobin

Red blood cells are red in colour due to the presence of a red pigment called haemoglobin. Red blood cells are carriers of oxygen. Red blood cells carry oxygen from lungs to all the cells of the body. It is the haemoglobin present in red blood cells which carries oxygen in the body. Haemoglobin performs a very important function of carrying oxygen from lungs to the body tissues. Haemoglobin also carries some of the carbon dioxide from body tissues to lungs.

Thus, the correct answer is option C.
