WebBecause the concentration of Na + is higher outside the cell than inside the cell by a factor of 10, ions will rush into the cell, driven by both the chemical and electrical gradients. Because sodium is a positively charged ion, as it enters the cell it will change the relative voltage immediately inside the cell membrane. Web30 okt. 2024 · Answer: A.

WebWe can see from this diagram that the Na ^+ + and Cl ^- − ions naturally position themselves next to one another in space due to the shared electrostatic attractions between them. The ions are then held in place by their very strong ionic bonds. WebThe positive ions move one way and the negative ions move the other way. The speed of movement is remarkably slow. It is perhaps only one millimetre a minute or less. Using a larger potential difference can increase the speed, but then much more stringent safety precautions have to be taken. Even so, the speed is never great.

WebBut: When an action potential occurs, only a tiny, tiny amount of ions (<0.001%) need to move across the membrane to change the membrane potential. This is because membrane potential changes are not determined by concentration changes, but by permeability … Web12 apr. 2024 · The positive sodium ions move towards the negatively charged electrode (the cathode). When they get there, each sodium ion picks up an electron from the electrode to form a sodium atom. These float to the top of the melt as molten sodium metal.
