Transport and Exchange of Carbon Dioxide

• Carbon dioxide diffuses into RBCs and combines
  with water to form carbonic acid (H2CO3), which
  quickly dissociates into hydrogen ions and
  bicarbonate ions
• In RBCs, carbonic anhydrase reversibly catalyzes
  the conversion of carbon dioxide and water to
  carbonic acid
