Select incorrect statement for permeability

Options

A. It depends on the membrane composition
B. It depends on the chemical nature of the solute.
C. It depends on the chemical potential inside cell
D. The extent to which a membrane permits or restricts the movement of a substance is called permeability.

Answer

### Step-by-Step Solution

1. **Understanding Permeability**:
- Permeability refers to the ability of a membrane to allow substances to pass through it. It indicates how easily a substance can move across the membrane.

2. **Key Factors Affecting Permeability**:
- Permeability is influenced by several factors:
- **Membrane Composition**: The materials that make up the membrane can affect how permeable it is to different substances.
- **Nature of the Solute**: The chemical properties of the solute (such as size, charge, and polarity) also determine how easily it can pass through the membrane.

3. **Identifying Incorrect Statements**:
- The question asks to select the incorrect statement regarding permeability.
- One of the statements mentioned is that permeability depends on the "chemical potential inside the cell." This is incorrect because permeability is primarily determined by the membrane's properties and the solute's characteristics, not the chemical potential inside the cell.

4. **Conclusion**:
- Therefore, the incorrect statement regarding permeability is that it depends on the chemical potential inside the cell.
