What a great Q'n. The short non-Answer is that potassium ions also "do not cross" the Cell membrane. The Sodium-Potassium pump system [in Neurons] could not function if Na+ and K+ ions were free to travel unimpeded.

How does a high consentration of salt affect cells?

You are looking at a hypertonic solution, where there is a higher amount of salt outside the cell than there is inside the cell. The water inside the cell will diffuse out, which causes the cell to shrink. This is why your fingers shrivel in the bathtub. The opposite will happen in a hypotonic solution. The cell has more salt than the outside, and the water will diffuse into the cell, causing it to swell.


When a red blood cell is placed in a hypertonic solution is water the only thing diffusing or will the salt diffuse as well in an attempt to achieve equilibrium?

Both water and salt will diffuse in an attempt to reach equilibrium. In a hypertonic solution, water will move out of the red blood cell into the solution, causing the cell to shrink. At the same time, salt from the solution will move into the red blood cell to balance the concentration gradient.


When is a cell most likely to diffuse into a cell when?

I believe the answer is when it is uncharged.


In Osmosis does salt diffuse through a membrane?

Yes


How does drinking salt water affect your cell membrane?

i think you mean to ask what effect salt water has on a cell. if you were to introduce a cell into an environment that has a higher salt concentration that its own internal concentration, you would create a concentration gradient (difference). water would diffuse across the cells membrane OUT of the cell and into the external environment in a process called osmosis, in an attempt to even out the differences in concentration by diluting the outside saltier environment. the result would be a shrivelled more "dehydrated" or hypertonic cell.


What will not diffuse through the cell membrane?

Glucose


Does water diffuse towards an area with more salt or less salt?

water follows sodium


Which molecule would be unable to diffuse through a cell membrane?

A molecule that is too large or charged would be unable to diffuse through a cell membrane.


Glucose is a molecule that can move across the cell membrane if the concentration of glucose is high or inside the cell than outside the cell then what will happen by the process of diffusion?

glucose molecules will diffuse out of the cell. apex


What part allows only certain subsTances to diffuse into and out of the cell?

The cell part that allows only certain substances to diffuse into and out of the cell is called the semi permeable membrane. This allows good substances to enter the cell.


What changes would take place in the chlamydomonas cell if it were transfered to sea water?

If a Chlamydomonas cell is transferred to sea water, it may experience changes in its osmotic balance due to the different salt concentration. The cell may need to regulate its water and ion levels to prevent dehydration or bursting. Additionally, the cell may adapt its metabolic processes to utilize the different nutrients available in the sea water.


Why does a cell diffuse items into the cell?

The cell needs food and water so it diffuses it to maintain health.
