Practice questions on Acid Base Balance
What is the primary role of hemoglobin in acid-base balance?
- Eliminates CO2 from lungs
- Acts as intracellular protein buffer binding hydrogen ions
- Produces bicarbonate in kidneys
- Regulates aldosterone secretion
Answer: B. ** Hemoglobin acts as an intracellular protein buffer by binding with hydrogen ions, helping prevent large fluctuations in pH within red blood cells and contributing to overall buffering capacity. ---
