The oxygen-binding proteins hemoglobin and myoglobin differ in that hemoglobin functions as a tetramer in red blood cells, whereas myoglobin functions as a monomer in muscle cells. The globular structure of myoglobin and each hemoglobin monomer involves eight ? -helical segments. Is it the primary, secondary, tertiary, or quaternary structure that differs most between these two proteins? Explain.
