Question

Which three of the following statements accurately describe the blood buffering system in humans? The blood buffering system... utilizes the H_2CO_3/HCO_3 conjugate acid/base pair, depends on the ionization of H_2PO_4-. utilizes the acetic acid/acetate conjugate acid/base pair, regulates the blood pH at 7.4 +/- one pH unit. is facilitated by the enzyme carbonic anhydrase, which interconverts carbon dioxide and water to carbonic acid (ionizes into bicarbonate and H^+). maintains the pH of blood near 7.4.

Explanation / Answer

maintains the pH of blood near 7.4
