Question

Haemoglobin is found in?

Answer 1

Hint: Haemoglobin is a protein that is helpful in carrying oxygen from body organs and tissue and transporting carbon dioxide from organs and tissue back to the lungs. The normal haemoglobin for a man is 13.5 to 17.5 grams per decilitre for a woman it is 12 to 15 grams per decilitre.

Complete answer:
Haemoglobin is an iron containing protein that is found in blood mostly in many animals. haemoglobin is derived from a Greek word for “haem” which means blood in “globin” means sphere. It is denoted with Abbreviation Hb.
Haemoglobin has a red pigment that gives red colour to the cell.
About $70\mathrm{\%}$ of the body's iron is found in haemoglobin.
Haemoglobin is made up of 4 amino acids, each chain contains a compound home that has an iron centre and helps in transport of oxygen in blood streams. Haemoglobin has two unstable stages that are reversible. In an oxygenated state it is called oxyhaemoglobin and it is bright red colour whereas in a reduced it is blue in colour and it is called as Deoxyhaemoglobin.
Haemoglobin is found in red blood cells.

Note:
The changed shape of haemoglobin structure will lead to diseases like Sickle Cell anaemia. It is an inherited red blood disorder. In Sickle Cell anaemia the RBC become abnormal in shape and are not able to carry oxygen as required.
