BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Hemoglobin is an allosteric protein. When one heme group in hemoglobin binds oxygen, it is easier for successive oxygen molecules to bind at the remaining three sites.

Detailed explanation-2: -You can think of hemoglobin as the iron ("heme"), oxygen transport protein, ("globin") found in red blood cells. It’s the hemoglobin that gives red blood cells their color, too.

Detailed explanation-3: -Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body. Checking the number of red blood cells in the blood is usually part of a complete blood cell (CBC) test. It may be used to look for conditions such as anemia, dehydration, malnutrition, and leukemia.

Detailed explanation-4: -Hemoglobin is involved in the transport of other gases: It carries some of the body’s respiratory carbon dioxide (about 20–25% of the total) as carbaminohemoglobin, in which CO2 is bound to the heme protein.

Detailed explanation-5: -Haemoglobin protein is a transport protein or carrier protein because it carries oxygen from lungs to the other part of the human body.
