Passive transport
|
the process of moving substances without any input of the cell |
|
|
Diffusion
|
the movement of molecules from an area of higher concentration to an area of lower concentration |
|
|
Concentration Gradient
|
the difference in the Concentration of molecules across a distance |
|
|
Equilibrium
|
the concentration of molecules will be the same throughout the space the molecules occupy |
|
|
