Witryna29 cze 2024 · The sodium and chloride ion concentrations are lower inside the cell than outside, and the potassium concentration is greater inside the cell. These concentration differences for sodium and potassium are due to the action of a membrane active transport system which pumps sodium out of the cell and potassium into it.

For example, the sodium-potassium pump maintains a high concentration of sodium ions outside of the cell. Therefore, if the cell needs sodium ions, all it has to do is open a passive sodium … WitrynaThe negative charge within the cell is created by the cell membrane being more permeable to potassium ion movement than sodium ion movement. In neurons, potassium ions are maintained at high …

Witryna12 kwi 2024 · There are many ions in the cell and extracellular space, but not all of them can pass through the cell membrane. Those who can, are called diffusible ions (sodium, potassium, calcium, and chloride), and those who can’t are non-diffusible ions (proteins).
