Overall none, or the cell would swell or shrink until the osmotic pressure becomes the same.
But :
most of the sodium is outside & most of the potasium is inside.
most of the proteins are inside
most of the sugar is outside (depending on insulin).
yes there is the lesser concentration of potassium ions outside the cell
their concentration is higher inside
during action potentiol k ions move inside from outside on the other hand n ions move outside from inside
their movement is associated with sodium potassium pumps
these pumps work with the utilization of energy which comes from ATP (adenoseine triphosphate)
in this way inside of the cell become more negative than outside and the cell come into action potentiol condition
There is more potassium inside and more sodium outside
That depends on what the cell is doing.
outside
Through the process of osmosis, the water inside the cell would leave the cell in order to equalize the concentration of water relative to salt in and outside the cell. The cell would shrink. Salt is not passing through at all.
The inside of a typical cell is posotive in respect to the outside. I got this out of my biology book.
If there is the concentration of substance inside the cell is lesser than outside and cell membrane is permeable to the substance.
A solution in which the salt concentration is greater outside the cell than inside the cell is known as
What ions are found on the outside and on the inside of an axon

out of the cell, against the concentration gradient.The calcium pump moves calcium ions out of the cell - from the cytoplasm to the extracellular fluid. Because the calcium concentration is much higher outside the cell compared to the inside, this transport is against the calcium concentration gradient. Inside calcium concentrations often increase in response to hormones and nerve input. Calcium pumps are important in terminating these responses by returning calcium concentrations to resting levels.
Unlike skeletal muscles, cardiac muscles need extracellular calcium ions in order to perform contractions. The sodium-calcium exchanger is the protein that facilitates this transfer, trading calcium from outside the cardiac cell with sodium inside the cell.
Salt is a solute, when it is concentrated inside or outside the cell, it will draw the water in its direction. This is also why you get thirsty after eating something salty.
Outside the cardiac muscle cell
outside of a plant cell

It is a cell wall. It is on the OUTSIDE of the cell, as opposed to the cell membrane, which is INSIDE the cell. -XOXOXO <3 It is on the OUTSIDE of the cell, as opposed to the cell membrane, which is INSIDE the cell. -XOXOXO <3
