Movement of molecules across the cell membrane - BBC Bitesize

WebIn cells, some molecules can move down their concentration gradients by crossing the lipid portion of the membrane directly, while others must pass through membrane proteins in a process called facilitated diffusion. Here, we’ll look in more detail at membrane permeability and different modes of passive transport. WebActive transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" - against a concentration gradient. The active transport of small molecules or ions across a cell membrane is generally carried out by transport proteins that are found in the membrane. Larger molecules such as starch can also be actively ...
