What wiil happen when R.B.Cs are kept in 10% glucose solution ?

Answer

### Step-by-Step Solution:

1. **Understanding Red Blood Cells (RBCs)**:
- RBCs, or red blood cells, are crucial components of blood that contain hemoglobin, which is responsible for transporting oxygen and carbon dioxide throughout the body.

2. **Identifying the Solution**:
- The question involves placing RBCs in a 10% glucose solution. This solution has a higher concentration of solutes (glucose) compared to the fluid inside the RBCs.

3. **Understanding Osmosis**:
- Osmosis is the movement of water across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. In this case, the RBCs are in a hypertonic solution (10% glucose).

4. **Effect of Hypertonic Solution on RBCs**:
- When RBCs are placed in a hypertonic solution, water will move out of the RBCs into the surrounding solution to balance the concentration of solutes. This process is known as exoosmosis.

5. **Resulting Change in RBCs**:
- As water leaves the RBCs, they will lose volume and shrink. This phenomenon is referred to as crenation.

6. **Conclusion**:
- Therefore, when RBCs are kept in a 10% glucose solution, they will undergo shrinkage due to the process of exoosmosis.

### Final Answer:
When RBCs are kept in a 10% glucose solution, they will shrink due to exoosmosis.
