Explain the importance of haemoglobin
Answers
This molecule is responsible for carrying oxygen from the lungs to other tissues of the body, and collects the carbon dioxide from the tissues and returns it to the lungs.
Hemoglobin is made up of four protein molecules – two alpha-globulin chains and two beta-globulin chains.
Each of the globulin chain contains an iron-containing porphyrin compound called heme. Heme compound contains iron atom in it and is crucial for oxygen and carbon dioxide transportation in our blood.
The red color of the hemoglobin is because of this iron compound.
Other role of Hb is maintaining the normal shape of the RBCs.
The exchange of gases occurs because of many biochemical reactions .
→ Haemoglobin present in red blood cell. It gave red colour to blood. It carry oxygen from our lungs to rest of the body. It helps in absorption of minerals and other nutrients. It also plays a important role in maintaining the shape of the red blood cells.
→ Whenever it react with oxygen it is known as oxyhaemoglobin amd when it react with carbon dioxide it is known as carboxyhaemoglobin. Addition of oxygen and carbon dioxide releases a gas named nitric gas. Nitric gas helps in regulation of blood pressure.
→ Haemoglobin is made up of 4 molecules of proteins that are joined together. Each haemoglobin carries 4 molecules of oxygen and it carries carbon dioxide in the form of bicarbonate.
→ Normal concentration of Haemoglobin in blood :-
* In female = 11 - 15 g/100 ml of blood.
* And in male = 12 - 17 g/100 ml of blood.
→ Anemia is a disease which occurs due to deficiency of haemoglobin in our body.
