Question

The chloride shift refers to the

A. effect of chloride ions on the oxygen dissociation curve
B. exchange of chloride ions for bicarbonate ions across the red blood cell membranes
C. exchange of chloride ions for carbon dioxide across alveolar cell membranes
D. effect of chloride ions on hydrogen ion diffusion from red blood cells
E. exchange of chloride ions for hemoglobin across the RBC membrane

Answer 1

The chloride shift refers to the exchange of chloride ions for bicarbonate ions across red blood cell membranes.

Step-by-step explanation:

The chloride shift refers to the exchange of chloride ions for bicarbonate ions across red blood cell membranes.

Inside red blood cells, carbon dioxide is converted into bicarbonate ions, which are then transported out of the red blood cells in exchange for chloride ions. This exchange allows for the continued uptake of carbon dioxide into the blood and helps maintain the electrical charge of the red blood cells and blood.
