Hamburger shift is also called :

Options

A. Hydrogen shift
B. Bicarbonate shift
C. Chloride shift
D. Sodium shift

Answer

**Step-by-Step Solution:**

1. **Understanding Hamburger Shift**: The Hamburger shift refers to a physiological process that occurs in red blood cells (RBCs) during the transport of carbon dioxide (CO2) in the blood.

2. **Role of CO2 in RBCs**: When CO2 enters the RBCs, it reacts with water to form bicarbonate (HCO3-). This reaction is facilitated by the enzyme carbonic anhydrase.

3. **Exchange of Ions**: As bicarbonate ions are produced inside the RBCs, they need to be transported out into the plasma. To maintain electrical neutrality, chloride ions (Cl-) move into the RBCs from the plasma. This exchange of bicarbonate and chloride ions is what defines the Hamburger shift.

4. **Terminology**: The Hamburger shift is often referred to as the "chloride shift" because it is the chloride ions that are entering the RBCs while bicarbonate ions are leaving.

5. **Conclusion**: Therefore, the Hamburger shift is also known as the chloride shift.

**Final Answer**: Hamburger shift is also called the chloride shift.
