Question

why myoglobin has single subunit but performs same function as that of haemoglobin that has 4 subunits ?​

Answer 1

Answer:

Haemoglobin is made up of four polypeptide subunits, two alpha (α) subunits and two beta (β) subunits. Each of the four subunits contains a heme ( contains iron) molecule, where the oxygen itself is bound through a reversible reaction, meaning that a haemoglobin molecule can transport four oxygen molecules at a time.
