Question:

$\text{A gas that has the greatest affinity for hemoglobin is:}$

Options:

1. $\text{CH}_4$
2. $\text{NO}$
3. $\text{O}_2$
4. $\text{CO}_2$

Solution:

$\text{HINT: NO has great affinity for Hb.}$ $\text{Explanation:}$ $\text{STEP 1: Haemoglobin is a globular protein consisting of two types of globin as two alpha chains and two beta chains. It is bound with a prosthetic group as heme.}$ $\text{Heme consists of a complex organic ring structure which is bound with an iron atom.}$ $\text{Iron has six coordination bonds, four with nitrogen atoms as a part of a porphyrin ring and two perpendiculars to porphyrin.}$ $\text{Haemoglobin has higher affinity for smaller molecules like Carbon Monoxide, Nitrogen Oxide etc.}$ $\text{STEP 2: NO binds rapidly to haem iron in Hb and once bound, the NO activity is largely irretrievable, the binding is purportedly so tight as to be unaffected by O}_2 \text{ or CO.}$ $\text{So, NO has the greatest affinity toward haemoglobin.}$
