Haemoglobin has highest affinity for A)Oxygen B)Carbon dioxide C)Carbon monoxide D)Nitrogen
Option A) Hemoglobin is the iron-containing oxygen-transport metalloprotein in the red blood cells. It is responsible for binding oxygen in the lung and transporting the oxygen throughout the body to be used up in aerobic metabolic pathways. The oxygen binding properties of hemoglobin exist because of the interaction between oxygen and the iron atom of the heme groups and hemoglobin's quaternary structure.
