Detailed explanation-1: -Haemoglobin is made up of a simple protein, called globin and a non-protein also known as haem.
Detailed explanation-2: -Hemoglobin is a complex protein which has a quaternary structure and contains iron. There are four subunits in the hemoglobin molecule-two alpha subunits and two beta subunits.
Detailed explanation-3: -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-4: -Hemoglobin is a conjugated protein whose prosthetic group, heme, gives it its typical intense red color.
Detailed explanation-5: -(a) Simple proteins. On hydrolysis they yield only the amino acids and occasional small carbohydrate compounds. Examples are: albumins, globulins, glutelins, albuminoids, histones and protamines. (b) Conjugated proteins. These are simple proteins combined with some non-protein material in the body.
