oxygen through red blood cells. Presence of haemoglobin gives

metallic taste to the blood. Haemoglobin is an intracellular

protein which acts as a primary vehicle for transporting 97% of

oxygen in the blood.

Answer 2

The correct answer is OPTION B: It has a high oxygen and carbon dioxide affinity.

• Any substance that improves the ability of blood to carry oxygen is referred to as a respiratory pigment.
• The amount of oxygen that red blood cells can transport to our tissues and organs is known as their oxygen-carrying capacity.
• In humans and most other animals, the protein haemoglobin is the most prevalent respiratory pigment.
• Red blood cells contain haemoglobin, a protein molecule that transports oxygen from the lungs to the tissues and returns carbon dioxide from the tissues to the lungs.
