Question

There is a higher sodium concentration on the inside of the cell than there is on the outside of the cell. How will the sodium particles move and by what process? Sodium will move from the outside of the cell to the inside of the cell by osmosis. Sodium will move from the inside of the cell to the outside of the cell by osmosis. Sodium will move from the outside of the cell to the inside of the cell by diffusion. Sodium will move from the inside of the cell to the outside of the cell by diffusion.

Answer 1

Answer;

-Sodium will move from the inside of the cell to the outside of the cell by diffusion.

Explanation;

-Diffusion involves the movement of molecules or ions from a region of high concentration to a region of low concentration (down the concentration gradient).

-If molecules are too large to diffuse through the cell membrane, they must pass through ion channels.

-Ion channels are trans-membrane proteins embedded in the cell membrane that offer an opening for slightly larger molecules across the cell membrane. They are also called facilitated diffusion, because molecules move from high to low concentration in a process facilitated, or enabled, by transport proteins.

-Examples of ions: Potassium(K+) Sodium(Na+) Calcium(Ca+) and Chloride(Cl-). The definition of Ion channels is: when they are open, charged ions can pass through the cell membrane, entering or leaving the cell.

Answer 2

Sodium will move from the inside of the cell to the outside of the cell by diffusion.

Step-by-step explanation:

A difference in concentration of a substance in two regions induces movement of that substance from the area of high concentration to the area of low concentration. Since the movement is according to a concentration gradient there is no need for energy expenditure. This is called passive diffusion.

In this case passive diffusion of sodium will occur. If a substance has to be moved against its concentration gradient energy is required and this process is called active diffusion.
