Question

Which of the following counteracts the movement of bicarbonate ions from the RBC?

A) chloride shifting
B) the Haldane effect
C) release of hydrogen ion
D) the Bohr effect

Answer 1

A) chloride shifting

Step-by-step explanation:

• Chloride shifting involves the exchange of bicarbonate (HCO3-) and chloride ions (Cl-) across the red blood cells membrane.
• Most carbon dioxide in the body is transported in the form of bicarbonate in the blood. As the blood flows in the tissues, carbon dioxide gas diffuses into the red blood cells and is converted to bicarbonate.
• The transport of bicarbonates into the red blood cells is in exchange for chloride ions. Which is referred to as chloride shifting.
