|
are those that require no metabolic energy (ATP) from the cell but rely solely on physical properties of the substances themselves. |
Passive processes |
|
|
require energy (ATP) expenditure by the cell to move substances whose physical properties prevent their moving on their own. |
Active transport processes |
|
|
can be defined as the net movement of particles from an area of high concentration to an area of low concentration. |
Diffusion |
|
|
