What is the role of carbonic anhydrase? Show by a series of reactions,
how carbonic anhydrese starts the reactions leading to the fomation of haemoglobic acid
Answers
Answer:
carbonic anhydrase which is found in the red blood cell catalyzes a reaction converting CO2 and water into carbonic acid which dissociate into protons and bicarbonate ions.
carbonic anhydrase speeds up the reaction of carbon dioxide reacting with water to produce hydrogen protons and bicarbonate ions.
haemoglobinic acid A very weak acid formed inside red blood cells when hydrogen ions combine with haemoglobin. The presence of the hydrogen ions, which are produced by the dissociation of carbonic acid (see carbonic anhydrase), encourages oxyhaemoglobin to dissociate into haemoglobin and oxygen (see Bohr effect). The oxygen diffuses into the tissue cells and the haemoglobin acts as a buffer for the excess hydrogen ions, which it takes up to form haemoglobinic acid.
