All cells contain ion pumps that use the energy of atp hydrolysis to pump ions across the plasma membrane. these pumps create an electrochemical gradient across the plasma membrane that is used to power other processes at the plasma membrane, including some transport processes. in animal cells, the main ion pump is the sodium-potassium pump. complete the diagram below using the following steps. drag the correct white label to the white target, indicating how many ions move through the pump and in which directions. drag the pink labels to the pink targets, indicating the relative concentrations of na^+ and k^+ inside and outside the cell. drag the blue labels to the blue targets, indicating the relative charges inside and outside the cell.
