During chloride shift or Hamburger phenomenon, when the whole blood is saturated with CO₂, following changes occurs. Which one of them is not correct?

Bicarbonate content of plasma and corpuscles increase

Chloride content of plasma diminished and that of the cell is increased

Total base of blood remain unchanged

Water content and volume of corpuscles decrease

Water content and volume of corpuscles decrease

According to Hamburger phenomenon, when the whole blood is saturated with carbon dioxide, the following changes are seen

(i) The bicarbonate contents of plasma and corpuscles increase.
(ii) The chloride content of plasma lo diminished and that of the cell is increased.
(iii) The total base (cations) of both plasma and corpuscles remain unchanged.
(iv) The water content and the volume of corpuscles increase.
(V) When the carbon dioxide is removed from the blood reverse changes takes place.
(vi) When CO₂, enters the blood, Cl^- from plasma enters RBCs leaving Na⁺ behind. When CO₂ escapes from blood Cl^- leaves the cell and combines with Na+ again. Due to this alternate movement of Cl ions, this phenomenon is called chloride shift.

Which one of the following elements is an activator for both ribulose biphosphate, carboxylase oxygenase and phosphoenol-pyruvate carboxylase in photosynthetic carbon fixation?
