Question

CO2+Hb = _ - (A) Oxyhemoglobin (B) Carboxyhemoglobin (C) Carbaminohemoglobin (D) None of these​

Answer 1

Answer:

Haemoglobin (Hb or Hgb) is a protein in red blood cells that carries oxygen to cells and carbon dioxide to the lungs.

CO

2

is carried by haemoglobin as carbamino-haemoglobin. Binding of CO

2

to Hb occurs because in the tissues the pCO

2

is high and pO

2

is low.

About 20-25 per cent CO

2

is transported in the form of Carbaminohaemoglobin.

Hence CO

2

O2 combines with Hb to form Carbaminohaemoglobin.

So, the correct answer is 'Carbaminohaemoglobin'.
