Question

Buffer systems present in blood help in maintaining the neutral pH of blood. Which is the most important buffer system present in blood? A.Carbon monoxide-hydrogen buffer. B. Carbonic acid-bicarbonate buffer. C.Carbon dioxide-bicarbonate buffer

Answer 1

The correct option is B.

A buffer refers to an aqueous solution which resist changes in pH when acids or bases are added to it. Also addition or removal of water from a buffer system does not change the pH of the system significantly. Buffers typically are made up of pairs of weak acid and their conjugate base or pairs of weak base and their conjugate acids. Maintaining the ideal pH is very important in living organisms, blood buffers help living organisms to maintain constant blood pH.

Answer 2

I think the correct answer from the choices listed above is option B. Buffer systems present in blood help in maintaining the neutral pH of blood. The most important buffer system is the Carbonic acid-bicarbonate buffer. Hope this answers the question.
