bicarbonate ions in the blood can absorb hydrogen ions, keeping ph balanced when the blood becomes too acidic. bicarbonate is acting as a(n) in blood.



Answer :

Bicarbonate is acting as a Buffer in blood.

Metabolic acidosis occurs when acids and insufficient bases build up in the body. Under normal conditions, the kidneys work to excrete acid in the urine and increase the reabsorption of bicarbonate from urine to neutralize the excess acid and maintain normal pH.

Shifts to the left as the ratio of bicarbonate to carbonic acid increases and more free acid is incorporated, thereby increasing pH. It functions as a component of the major buffer system, thereby playing an important role in pH homeostasis. Bicarbonates can also be used by a variety of ion transporters, often operating in coupled systems to transport other ions and organic substrates across cell membranes.
