During `CO_(2)` transport, `HCO_(3)^(-)` diffuses from erythrocytes to plasma and in turn upsets the ionic balance momentraily. In order to keep the ionic balance, an equal number of `Cl^(-)` pass into the erythrocyes from plasma. The process is known as

Options

A. Hamburger phenomenon
B. bicarbonate shift
C. carbonation
D. Bohr's effect.

Answer

A

Explanation

About `70%` of `CO_(2)` is converted to bicarbonate ions `(HCO_(3)^(-))` and tranported in plasma. `CO_(2)` diffuse into RBCs. Combines with water and forms carbonic acid `(H_(2)CO_(3))`. `H_(2)CO_(3)` being unstable quickly dissociates into `H^(+)` and `HCO_(3)`. `HCO_(3)` ios are quite diffusible. Therefore, `HCO_(3)^(-)` diffuses from RBCs into the plasma. To maintain the ionic balance `Ci^(-)` diffuses from RBCs from the plasma into the RBCs. the exchange is called chloride shift or Hamburger's phenomenon.
