endoplasmic reticulum
It makes and packages things to be transported out of the cell.
it moves materials from areas of high concentration to areas of low concentrationit moves materials of high concentration to areas of low concentration
The process of moving materials across the cell membrane without the expenditure of energy is called passive transfer
well water moves all the small particles
active transport
Endoplasmic Reticulum =)
The canal network moves certain materials within a cell
Transport proteins that are pumps differ from those that are channels in that when it pumps, it moves materials against concentration gradient. Other wise, from low to high concentration levels. Channels move materials down a concentration gradient, requiring no energy expenditure by the cell. From high concentration to low concentration levels.
