CO2 Transport

Published by Darron Toy on



from tissues carbon dioxide diffuses into blood where a small amount of it dissolves the remaining molecules enter the red blood cells where they combine with water and eventually convert to hydrogen and bicarbonate ions an enzyme found only inside red blood cells speeds up the reaction 250 times the ions formed during this reaction can dissolve more easily than carbon dioxide itself these ions make it possible to transport large amounts of the gas in this bicarbonate form at the lung the bicarbonate reaction is reversed carbon dioxide diffuses out of blood and through the moist walls of the alveoli where exhaling removes it

Each carbonic anhydrase molecule, from what I am reading, can catalyze 10^4 to 10^6 reactions per second!  Unbelievable!

Carbonic anhydrase allows for a soluble form of CO2 which can then be transported in the blood……the CO2 transformed into the bicarbonate molecule also acts as a buffer in the blood to minimize pH swings.  Two, two, two mints in one!

That enzyme is called carbonic anhydrase, thank you for the video! very helpful

Everyone knows that H2O + CO2 —> H2CO3 + star wars sound effects
