Q. The correct statement in respect of protein haemoglobin is that it
A) Functions as a catalyst for biological reactions
B) Maintains blood sugar level
C) Act as an oxygen carrier in the blood
D) Forms antibodies and offers resistance to diseases
Explanation
(c)
Haemoglobin acts as oxygen carrier in the blood because four ${Fe}^{2 +}$ ions of each haemoglobin can bind with four molecules of $O_{2}$ and form oxyhaemoglobin.
$4Hb + 4O_{2}\ \rightarrow Hb_{4}O_{8}$
Oxyhaemoglobin
