: there is a higher concentration outside the cell, diffusion will cause more of the molecules to enter the cell, there is a lower concentration of molecules inside the cell, no ATP energy will be required to have molecules enter the cell, : there is a higher concentration inside the cell, diffusion will cause more of the molecules to leave the cell, passive transport will occur as molecules exit the cell, : the molecules have reached equilibrium, the number of molecules in and outside the cell is the same, the molecules are balanced in and outside of the cell,
