During Vigorous Physical Activity, the Bohr Effect Would Enhance the Delivery

During vigorous physical activity, the Bohr effect would enhance the delivery of oxygen to the tissues of the body. All of the following are associated with this effect at the tissues EXCEPT

A) a conformational change occurs that alters the pKa and hence the charge on the imidazole groups of the hemoglobin molecules.
B) the oxygen-hemoglobin association curve shifts to the right.
C) the tense form of hemoglobin is stabilized.
D) hydrogen ions are released from the hemoglobin to the tissues.
E) there are alterations in the salt linkages of the hemoglobin molecules.
