Subunits present in haemoglobin are

  • A
    2
  • B
    3
  • Correct answer
    C
    4
  • D
    5 .

Solution

One molecule of haemoglobin has 4 haeme groups, and each of them is capable of taking up one molecule of $\mathrm{O}_2$; therefore, oxyhaemoglobin may be depicted as $\mathrm{Hb}\left(\mathrm{O}_2\right)_4$.

Hence, the correct answer is option: 'C'.
