Answer:

hemoglobin, hemoglobin carries oxygen in the blood and it is made up of four subunits, two each of the α and β types.

Explanation:

Protein can have varying structures namely primary, secondary, tertiary and quaternary. An example of protein with a quaternary structure is hemoglobin.

What are different structures of protein?

The function of protein is completely dependent on its folding. Protein can be folded into many types.

The macromolecule protein can have the following structural classification:

  • Primary structure: It is a linear chain of amino acids.
  • Secondary structure: The linear chain folds to form secondary structure.
  • Tertiary structure: it involves further folding of protein chain.
  • Quaternaty structure: it is the spatial arrangement of the folded protein.

Hemoglobin is one of the proteins that exhibits quaternary structure.

Thus, hemoglobin is an example of a protein that has quaternary structure.
