Question

Quizplus · Accepted Answer

The interaction of two α and two β subunits to form a functional hemoglobin molecule represents quaternary structure, which refers to the arrangement of multiple protein subunits into a larger, functional protein complex. The primary structure refers to the linear sequence of amino acids in a single polypeptide chain, the secondary structure involves local folding patterns such as alpha-helices and beta-sheets, and the tertiary structure refers to the overall 3D conformation of a single polypeptide chain.
