Hey mate here is your answer
The efficiency of movement of substances in and out of a cell is determined by its volume to surface area ratio. Selected substances can move up a concentration gradient with the help of specialized molecules embedded in the membrane. This is called assisted diffusion or active transport.
Hope this answer will help you!!!
