    the hemoglobin molecule can bind multiple types of molecules, not just oxygen.

    B

    the four subunits of hemoglobin are able to bind together without need for any enzymatic catalysis.

    C

    the molecule can interact with other hemoglobin molecules to improve oxygen saturation.

    D

    each additional molecule of oxygen binding to hemoglobin makes subsequent binding of oxygen molecules easier.
