Which of the following counteracts the movement of bicarbonate ions from the RBCs?
A)Dalton's law
B)the Bohr effect
C)the chloride shift
D)ventilation-perfusion matching

Question

Quizplus · Accepted Answer

The chloride shift refers to the movement of chloride ions into the RBCs in exchange for bicarbonate ions that diffuse out. This exchange helps to maintain an electrical gradient and counteracts the movement of bicarbonate ions out of the RBCs. Dalton's law refers to the partial pressures of gases in a mixture and does not directly affect bicarbonate ion movement. The Bohr effect refers to the influence of carbon dioxide and pH on oxygen binding to hemoglobin and does not directly affect bicarbonate ion movement. Ventilation-perfusion matching refers to the matching of air flow and blood flow in the lungs and does not directly affect bicarbonate ion movement.
