Answer:
Correct Answer: C
Solution:
Conjugated proteins are the proteins which are formed by the binding of a simple protein with a non-protein prosthetic group.
Conjugated chromoproteins are pigment-protein complexes.
Hemoglobin is one such conjugated chromoprotein.
It is composed of a simple protein called ?globin? and non protein iron $ (F{e^{2+}}) $ porphyrin complex called ?heme?.
100 ml of blood contains about 15g of hemoglobin.
Four $ Fe^{2+} $ ions of heme can loosely bind to up to four molecules of oxygen, thus enabling hemoglobin to carry oxygen.
