Cholera petients are provided with transfer of electrons ?

Options

A. NaCl is component of blood, maintains RBCs and helps dissolve proteins
B. `Na^(+)` is required for water transport across plasma membrane
C. Cl- is essential component of blood plasma
D. Cl- helps form HCl in stomach.

Answer

To answer the question regarding cholera patients and the transfer of electrons, we need to analyze the statements provided and determine which one is correct in relation to the treatment of cholera.

### Step-by-Step Solution:

1. **Understanding Cholera**: Cholera is an infectious disease characterized by severe diarrhea and dehydration. The primary concern in cholera patients is the loss of fluids and electrolytes, particularly sodium ions (Na+).

2. **Evaluating the Statements**:
- **Statement A**: "NaCl is a component of blood which maintains RBCs and helps dissolving proteins."
- This statement is incorrect. While NaCl is important for various bodily functions, it does not specifically maintain red blood cells (RBCs) or help in dissolving proteins.

- **Statement B**: "Na+ is required for water transport across the plasma membrane."
- This statement is correct. Sodium ions play a crucial role in the transport of water across cell membranes, particularly in the kidneys and intestines. In cholera treatment, saline solutions (which contain sodium) are administered to help retain water in the body and combat dehydration.

- **Statement C**: "Cl- is an essential component of blood plasma."
- This statement is misleading. While chloride ions are present in blood plasma, they are not specifically essential in the context of cholera treatment.

- **Statement D**: "Chloride ions help in HCl formation in the stomach."
- This statement is incorrect. Hydrochloric acid (HCl) is produced by gastric glands in the stomach, and while chloride ions are involved in the overall process, they do not directly help in its secretion.

3. **Conclusion**: Based on the evaluation of the statements, the correct answer is **B**: "Na+ is required for water transport across the plasma membrane." This is significant in the context of treating cholera patients, who lose a lot of sodium and water.

### Final Answer:
The correct statement regarding cholera patients and the transfer of electrons is **B**: "Na+ is required for water transport across the plasma membrane."
