Detailed explanation-1: -Hemoglobin is a protein found in red blood cells. It contains iron, which allows it to transport oxygen. Each hemoglobin molecule can bind up to four oxygen molecules. This way, it can transport the oxygen from the lungs to the tissues that need it.
Detailed explanation-2: -Hemoglobin contains iron, which allows it to pick up oxygen from the air we breathe and deliver it everywhere in the body. You can think of hemoglobin as the iron ("heme"), oxygen transport protein, ("globin") found in red blood cells.
Detailed explanation-3: -Haemoglobin is made up of a simple protein, called globin and a non-protein also known as haem(iron containing part)
Detailed explanation-4: -Hemoglobin forms an unstable reversible bond with oxygen. In the oxygenated state, it is called oxyhemoglobin and is bright red; in the reduced state, it is purplish blue.
