What are the organic compounds responsible for maintaining the body’s acid-base balance?
  1. Acetic acid and sodium chloride
  2. Carbonic acid and sodium bicarbonate
  3. Lactic acid and calcium carbonate
  4. Pyruvic acid and ammonium hydroxide
Explanation
Answer: B - The organic compounds responsible for maintaining the body’s acid-base balance are carbonic acid and sodium bicarbonate. Carbonic acid compensates for increased levels of sodium bicarbonate in the blood (alkalosis), and sodium bicarbonate buffers high levels of carbonic acid (acidosis). Alkalosis and acidosis both result from disruptions in normal respiration or excretion.
