How does haemoglobin help in tge transport of carbon dioxide?
Answers
Most of the carbon dioxide, however, is converted into bicarbonate. Carbonic anhydrase is an enzyme in the red blood cells that quickly converts carbon dioxide and water into bicarbonate and hydrogen ions. The equation for this reaction is as follows: Carbon dioxide and water are converted to bicarbonate and hydrogen ions, where HCO3- is bicarbonate and H+ is hydrogen ion.
CO₂ + H₂O <- -> HCO₃- + H+ While this reaction is reversible, as indicated by the double arrows, the high concentration of carbon dioxide pushes the reaction to the right. Bicarbonate diffuses into the plasma, where it is used as a much-needed pH buffer. hydrogen ion produced in the above reaction binds to hemoglobin, which causes the oxygen to be released from the hemoglobin. That released oxygen can then enter into the cells and be used to make the much-needed ATP.
