Each alpha and beta subunits of hemoglobin bind an oxygen molecule. the joining of these 4 subunits is essential to hemoglobin function. what level of protein structure is this describing? primary secondary tertiary or quaternary structure of a protein?

4 subunits = QUATernary (or so you'd think) Because there are 2 alpha and 2 beta subunits, there are only 2. Add in the joiner chain (J) and there are 3, making Hgb a tertiary

Quaternary structure of a protein describes how multiple polypeptides of a protein molecule interact with each other.
