WebAs sodium enters, the membrane potential of the cell decreases and becomes more positive. As the membrane potential changes, the electrical gradient decreases in strength, and after the membrane potential passes 0 mV, the electrical gradient will point outward, since the inside of the cell is more positively charged than the outside. WebSodium need channels to move into cell because if cell will let every ion to move into it then it will become toxic. In order to prevent this nerve cells regulated the entry of ions via ion gated channels. Another reason is that sodium cannot cross the cell via simple diffusion,it needs to be facilitated via channels.

WebActive transport allows cells to move a specific substance against its concentration gradient through a membrane protein, requiring energy in the form of ATP. For example, the sodium-potassium pump employs active transport to pump sodium out of cells and potassium into cells, with both substances moving against their concentration gradients.

WebThis starts with the opening of voltage-gated Na+ channels in the neuron membrane.
