When a solution containing equal moles of hemoglobin and myoglobin is bubbled with a small amount of O2: A. hemoglobin will dissociate into free dimers. B. hemoglobin will dissociate into free monomers. C. more of the dissolved O2 will bind to hemoglobin than myoglobin. D. more of the dissolved O2 will bind to myoglobin than hemoglobin. E. myoglobin will exchange with some of the subunits of hemoglobin to form hybrid myoglobin-hemoglobin proteins.
