Vedclass · Answer

(B) Haemoglobin $(Hb)$ consists of two main parts: the haem group and the globin protein chain.$CO_2$ does not bind to the iron $(Fe^{2+})$ in the haem group,as that is the site for $O_2$ binding.Instead,$CO_2$ binds to the amino group of the globin protein chain to form a compound known as carbaminohaemoglobin.The reaction is represented as: $Hb + CO_2 \rightleftharpoons HbCO_2$ (carbaminohaemoglobin).

To which part of $Hb$,$CO_2$ binds?
