a) the rate of HCO3 reabsorption is inversely proportional to the arterial PCO2
b) in respiratory acidosis, HCO3 reabsorption is reduced
c) changes in plasma chloride concentration are proportional to CHO3
concentration
d) in respiratory alkalosis, renal H+
secretion is increased
e) HCO3 reabsorption depends upon the rate of H+ secretion by the renal
tubular cells
