Vedclass · Answer

(D) Hemoglobin $(Hb)$ is a quaternary protein consisting of four polypeptide subunits: two $\alpha$-chains and two $\beta$-chains.Each polypeptide chain contains one heme group.Each heme group contains one iron $(Fe^{2+})$ atom at its center.Therefore,since there are four heme groups in one hemoglobin molecule,there are a total of four iron atoms present in one quaternary structure of $Hb$.

How many iron atoms are present in one quaternary structure of $Hb$ (hemoglobin)?
