Haemoglobin is a protein present in red blood cells that carries oxygen to all organs and tissues of the body.
It transports Carbon diOxide from organs and tissues to the lungs.
Iron is involved in the synthesis of many proteins and enzymes
Iron is found in haemoglobin and myoglobin. Haemoglobin is involved in the transportation of Oxygen and Carbon diOxide.
Myoglobin is a protein that is present in the muscles. It stores oxygen in the muscles.
To produce haemoglobin, cells need iron to build a component called Heme.
Heme is found in oxygen transportation proteins, such as Haemoglobin and Myoglobin.
The kidneys produce a hormone called Erythropoietin that stimulates heme production in the bone marrow.
Heme is largely synthesised in erythroid cells for incorporation into haemoglobin.
It is a ring-like organic compound known as porphyrin, to which an iron atom is attached. It also combines with globin proteins to form haemoglobin protein.
Each haemoglobin molecule is made of four globular protein subunits. Each subunit is composed of a protein chain associated with a heme group.
Learn the concept well and try to explain it to your friends too.
