How can Biological Buffer maintain the pH value?

WebDec 23, 2015 · pH = 4.76 +0.301029996. pH ≈ 4.79. So, with a buffer like this, you should expect the pH to stay generally close to or return to something close to 4.79, not 7, if the equilibrium were to be disturbed. If it were to become 7 for a long time, that would not be a very good buffer. Answer link. WebThe bicarbonate buffer system is an acid-base homeostatic mechanism involving the balance of carbonic acid (H 2 CO 3), bicarbonate ion (HCO − 3), and carbon dioxide (CO 2) in order to maintain pH in the blood and duodenum, among other tissues, to support proper metabolic function. Catalyzed by carbonic anhydrase, carbon dioxide (CO 2) reacts with …
