Ions move from high concentration to low concentration. Here the sodium concentration gradient is established. So Na+ movement occurs from outside to inside with transported proteins thats why facilitated diffusion.

Concentration Gradients and Sodium Transport
Concentration Gradients in Human Cells
Human cells maintain concentration gradients across their plasma membranes, meaning that there is a difference in the concentration of ions on either side of the membrane. In the case of sodium and potassium, human cells have a high concentration of sodium ions (Na+) outside the cell and a high concentration of potassium ions (K+) inside the cell.
Sodium Leak Channels
Sodium leak channels are specialized proteins present in the cell membrane that allow sodium ions to move across the membrane. These channels are always open, allowing the passive movement of sodium ions from areas of high concentration to areas of low concentration. However, the movement of sodium ions through these channels is not facilitated or actively controlled by the cell.
Options for Sodium Transport
Based on the given information, let's analyze the statements regarding sodium transport:
a) Move out of the cell by simple diffusion
This statement is incorrect. Sodium ions move into the cell by simple diffusion through the leak channels, not out of the cell. Simple diffusion is the passive movement of particles from an area of high concentration to an area of low concentration, and in this case, sodium ions move from outside the cell (high concentration) to inside the cell (low concentration) through the open sodium leak channels.
b) Move into the cell by simple diffusion
This statement is incorrect. Sodium ions move into the cell by simple diffusion through the leak channels, not out of the cell. As explained above, the concentration gradient favors the movement of sodium ions from areas of high concentration (outside the cell) to areas of low concentration (inside the cell).
c) Move out of the cell by facilitated diffusion
This statement is incorrect. Facilitated diffusion involves the movement of particles across a membrane with the help of specific carrier proteins. Sodium ions, in this case, do not require any specific carrier proteins for their movement across the membrane. They can freely move through the open sodium leak channels by simple diffusion, as explained earlier.
d) Move into the cell by facilitated diffusion
This statement is correct. Facilitated diffusion can involve the movement of particles across a membrane with the help of specific carrier proteins. However, in the case of sodium ions, their movement is not facilitated by carrier proteins. They move into the cell through the open sodium leak channels by simple diffusion, not facilitated diffusion.
In conclusion, statements a), b), and c) are incorrect regarding sodium transport, while statement d) is correct.
Concentration Gradients in Human Cells
Human cells maintain concentration gradients across their plasma membranes, meaning that there is a difference in the concentration of ions on either side of the membrane. In the case of sodium and potassium, human cells have a high concentration of sodium ions (Na+) outside the cell and a high concentration of potassium ions (K+) inside the cell.

Sodium leak channels are specialized proteins present in the cell membrane that allow sodium ions to move across the membrane. These channels are always open, allowing the passive movement of sodium ions from areas of high concentration to areas of low concentration. However, the movement of sodium ions through these channels is not facilitated or actively controlled by the cell.

Based on the given information, let's analyze the statements regarding sodium transport:

This statement is incorrect. Sodium ions move into the cell by simple diffusion through the leak channels, not out of the cell. Simple diffusion is the passive movement of particles from an area of high concentration to an area of low concentration, and in this case, sodium ions move from outside the cell (high concentration) to inside the cell (low concentration) through the open sodium leak channels.
b) Move into the cell by simple diffusion
This statement is incorrect. Sodium ions move into the cell by simple diffusion through the leak channels, not out of the cell. As explained above, the concentration gradient favors the movement of sodium ions from areas of high concentration (outside the cell) to areas of low concentration (inside the cell).
c) Move out of the cell by facilitated diffusion
This statement is incorrect. Facilitated diffusion involves the movement of particles across a membrane with the help of specific carrier proteins. Sodium ions, in this case, do not require any specific carrier proteins for their movement across the membrane. They can freely move through the open sodium leak channels by simple diffusion, as explained earlier.
d) Move into the cell by facilitated diffusion
This statement is correct. Facilitated diffusion can involve the movement of particles across a membrane with the help of specific carrier proteins. However, in the case of sodium ions, their movement is not facilitated by carrier proteins. They move into the cell through the open sodium leak channels by simple diffusion, not facilitated diffusion.
In conclusion, statements a), b), and c) are incorrect regarding sodium transport, while statement d) is correct.
