Adult human haemoglobin consists of 4 subunits. These subunits are
A
Two α and two γ chains
B
Three α and one β chain
C
Two α and two β chains
D
One α and three β chains
Explanation
Quaternary structure of haemoglobin consists of 4 subunits. Two of these are identical to each other. Hence, two subunits of α type and two subunits of β type together constitute the adult human haemoglobin (Hb). γ subunit is found in foetal Hb.
