WebA and B are correct. A, B and C are correct. When does hemoglobin act as a buffer? when it releases CO_2 and picks up H^+ when it releases O_2 and picks up H^+ when it picks O_2 and releases CO_2 when it converts CO_2 to HCO_3^- when it converts O_2 to CO_2 in the carbonic acid-bicarbonate buffer system HCO_3^- acts as a weak base. WebHemoglobin as a Buffer. Hemoglobin is the principal protein inside of red blood cells and accounts for one-third of the mass of the cell. During the conversion of CO 2 into bicarbonate, hydrogen ions liberated in the reaction are buffered by hemoglobin, which is reduced by the dissociation of oxygen. This buffering helps maintain normal pH.
