Passive transport
|
Movement of substances through a cell membrane without the use of cellular energy
|
|
|
Examples of passive transport
|
Diffusion, osmosis, and facilitated diffusion
|
|
|
Active transport
|
Energy-requiring process in which transport proteins bond with particles and move them through a cell membrane
|
|
|
Diffusion
|
A type of passive transport in cells in which molecules move from areas where there are more of them to areas where there are fewer of them
|
|
|
Endocytosis
|
Process by which a cell takes in a substance by surrounding it with the cell membrane
|
|
|
Exocytosis
|
Process by which vesicles release their contents outside the cell
|
|
|
Equilibrium
|
Occurs when molecules of one substance are spread evenly throughout another substance
|
|
|
Osmosis
|
A type of passive transport that occurs when water diffuses through a cell membrane
|
|
|
What is facilitated diffusion?
|
A process when transport proteins help large molecules enter a cell
