Passive Transport

Molecules move down the concentration gradient (high to low); no energy/ATP

Active Transport

Molecules move against the concentration gradient (low to high); requires energy/ATP

Facilitated Diffusion

Uses protein channels to cross the membrane without energy

Osmosis

Water diffusion across semi-permeable membranes from low to high concentration

Simple Diffusion

Small/non-polar molecules slip through the lipid layer of the membrane during passive transport

ATP stands for…

Adenosine Triphosphate

Eukaryotic cells

Transmembrane pumps are used by…

Prokaryotic cells

Endocytosis

A form of active transport that brings bulk materials into the cell through vesicles

Exocytosis

A form of active transport that moves material out of the cell
