Question: what are the structural and functional differences between myoglobin and haemoglobin?
Answer: The capability of the binding oxygen molecule, with the heme proteins, is what makes a difference in both the molecules. Haemoglobin is called as tetrameric hemoprotein, while myoglobin is called monomeric protein. Haemoglobin is found systematically all over the body, while myoglobin is found in muscles tissues only.
