Answer:
Explanation:
Haemoglobin is the major iron-containing pigment that helps in the transport of gases. Each haemoglobin molecule can carry a maximum of four molecules of oxygen. Binding of oxygen with haemoglobin is primarily related to partial pressure of O
2
. In alveoli, where there is high pO
2
, low pCO
2
, lesser H
+
concentration and lower temperature, the factors are all favourable for the formation of oxyhaemoglobin. In tissues,where low pO
2
, high pCO
2
, high H
+
concentration and high temperature exist, the conditions favourable for dissociation of oxygen from the oxyhaemoglobin. Every 100 ml of oxygenated blood can deliver around 4 ml of O
2
to tissues under normal physiological conditions. A 100ml of oxygenated blood can carry 20ml of O
2
. However, only 4 ml is delivered to the tissues.
Thus, the correct answer is '4%.'
