- B3.1 - Movement of molecules in and out of cells
- Osmosis: Movement of water; dilute solution to a concentrated solution; through a PPM.
- Active Transport: Against concentration gradient; require energy from respiration

- Replacing substances: Exercise uses glucose, water and ions are lost by sweat.
- Drinks: Most soft drinks contain water, sugar and ions. Sports drinks contain higher amounts of sugar to replace sugar used in energy release.

- Exchanging materials in humans
- Alveoli in the lungs - Tiny air sacs in the lugs where exchange of O and CO2 takes place; excellent blood supply; thin capillary walls for short diffusion path
- Villi in the small intestine: Large surface area for exchange; extensive network of blood capillaries to maximise absorption; thin walls short diffusion path
