A patient is hyperventilating. The "blowing off" of excessive carbon dioxide causes a decrease in blood H+ concentration
How can the carbonic acid-bicarbonate buffer system function to correct this imbalance?
CO2 + H2O ? H2CO3 ? H+ + HCO3-
A) HCO3- binds with H+ to form H2CO3 and lower pH
B) HCO3- binds with H+ to form H2CO3 and raise pH
C) H2CO3 dissociates to form more H+ and lower pH
D) H2CO3 dissociates to form more H+ and raise pH
