Which three statements accurately describe the blood buffering system in humans? - The blood buffering system utilizes the H2CO3/HCO3– conjugate acid/base pair. - The blood buffering system utilizes the acetic acid/acetate conjugate acid/base pair. - The blood buffering system is facilitated by the enzyme carbonic anhydrase, which interconverts carbon dioxide and water to carbonic acid, ionizing into bicarbonate and H+ . - The blood buffering system maintains the pH of blood near 7.4. - The blood buffering system depends on the ionization of H2PO4– .
