Cell Transport

We just reviewed Biomolecules and ended with Lipids which leads us to review CELL TRANSPORT

1. diffusion

2. facilitated diffusion

3. osmosis.

​​

​(does not require energy​)

​​Passive Transport

Active Transport

 relies on the use of energy to move substances into and out of cells. Usually, molecules are traveling against a concentration gradient.
