|
Passive processes |
Dependant on concentration differences, pressure or differences in kinetic energy |
|
|
Active processes (active transport + bulk transport) |
Require cellular energy in the form of ATP |
|
|
Simple diffusion definition |
The NET movement of PARTICLES from and area of high concentration of particles to an area of low concentration of particles until equilibrium is reached. |
|
|
Facilitated transport |
The net movement of particles from an area of high concentration to an area of low concentration with the aid of protein transported until equilibrium is reached |
|
|
Osmosis- the diffusion of water |
Net movement from an area of high concentration of water to an area of low concentration of water through a semi permeable membrane until equilibrium is reached. |
|
|
Filtration |
Movement of fluid and small particles through a membrane due to a difference in pressure on either side of the membrane. Eg the kidney tubes |
|
|
Active transport |
Allow movement of particles from an area of low concentration to an area of high concentration using carrier molecules in the cell membrane Cellular energy (ATP) is required |
|
|
Bulk transport- Endocytosis |
Intake of material in bulk into the cell -phagocytosis (cell eating) Pinocytosis (cell drinking) |
|
|
Bulk transport- exocytosis (secretion excretion) |
Removal of material in bulk from the cell |
