Passive and Active Transport

No energy is used [High]  [Low] (it’s the natural flow) This means it goes down a concentration gradient.

Answer the following questions for the picture. Write the ANSWER only. 1. _________ is the movement of water. 2. _______ ________ requires energy to move.

Essential Question: What are the property differences between Active Transport and Diffusion?

1. Facilitated diffusion: when protein channels help move molecules across the membrane. - does not require energy.

2. Active transport : cells move materials against a concentration gradient. - does require energy - carried out by transport proteins in membrane .

3. Endocytosis: taking material into the cell using part of the cell membrane.

4. Exocytosis: forces materials out of a cell when a vesicle fuses with the cell membrane.

Reminders: Quiz on Wednesday. Notecards due on Thursday. Test on Thursday.
