1 Part 2: Passive and Active Transport
8.1 Cellular Transport Part 2: Passive and Active Transport

2 Passive Transport Some things can pass through the plasma membrane by diffusion Water, lipids

3 Passive Transport Some things are too big or won’t pass through the bilipid layer Transport proteins can let through if going with concentration gradient Facilitated diffusion Sugars, amino acids

4 Passive Transport

5 Active Transport Movement of materials through a membrane against concentration gradient Uses energy

6 Active Transport

7 Transport of large particles
Endocytosis – cell surrounds and takes in particles from outside Exocytosis – materials moved out of the cell

Chapter 3. Passive Transport  Diffusion – molecules move spontaneously (no energy used) from an area of high concentration to an area of low concentration.

Diffusion Particles naturally travel from areas where they are crowded to areas where they are less crowded. http://www.indiana.edu/~phys215/lecture/lecnotes/lecgraphics/diffusion.gif.

Plasma Membrane  aka – Cell membrane  Separates the interior of ALL cells from the outside environment  Protects the cell.
