$HCO_{3}^{-}$

Vedclass · Answer

(A) Chloride shift,also known as the Hamburger phenomenon,occurs in response to the movement of $HCO_{3}^{-}$ ions.To maintain the electrostatic neutrality of the plasma,when bicarbonate ions $(HCO_{3}^{-})$ diffuse out of the red blood cells (RBCs) into the plasma,an equivalent number of chloride ions $(Cl^{-})$ diffuse from the plasma into the RBCs.This exchange ensures that the electrical balance is maintained during the transport of carbon dioxide.Therefore,the chloride shift is a direct response to the exit of $HCO_{3}^{-}$ ions from the RBCs.
