16.119 Hemoglobin (Hb) is a blood protein that is responsi-
ble for transporțing oxygen. It can exist in the proto-
nated form of HbH". The binding of oxygen can be
represented by the simplified equation
HbH + O, = Hb0, + H"
(a) What form of hemoglobin is favored in the
lungs where oxygen concentration is highest?
(b) In body tissues, where carbon dioxide is re-
leased as a result of metabolism, the medium is
more acidic because of the formation of carbonic
acid. What form of hemoglobin is favored under
this condition? (c) When a person hyperventilates,
the concentration of CO, in his or her blood de-
creases. How does this action affect the above
equilibrium? Frequently a person who is hyperven-
tilating is advised to breathe into a paper bag. Why
does this action help the individual?
