Quizplus · Accepted Answer

Carbonic acid generated from metabolically produced CO₂ is the major source of hydrogen ions in the body. Carbonic acid dissociates to form H+ ions and bicarbonate ions, which helps in maintaining the pH of the blood. Other options may contribute to hydrogen ion production, but they are not the primary source.
