the equilibrium of k+ and nat this tells us the nernst potential or the rmp of cell as an example assume the cell is 90% permeable to k+ . -90mv x 0.9=-81mv as an example assume the cell is 10% permeable to nat . +70mv x 0.1=+7mv ‘add the two voltages together to obtain the nernst potential or rmp of the cell . -81mv + 7mv=-74mv rmp = -74mv these pumps push 3 na+ ions out of the cell making cell less positive. they also pump 2 k+ ions into the cell which is one less positive charge coming in than leaving. na+ is higher outside the cell and k+ is higher inside the cell. overall leads to net negative charge. the pumps require atp to work because they are pushing both these ions against their concentration gradient. this pump contributes approximately -5 mv of the -70 mv average of …
