Cell Transport In da Club (~11 min)
2
Cell membrane All cells are surrounded by a flexible barriers = cell membrane
3
proteins are embedded within the lipid bilayer—
Carbohydrates also attach, carbohydrates proteins
4
Cell wall Many cells also have a strong layer around the membrane = cell wall
5
Concentration The cytoplasm of the cell is a solution of water with many substances dissolved with in it
6
Diffusion
7
Diffusion across membrane
8
Equilibrium
9
Osmosis There is more sugar on right side, so amount of water on right is less
12
Affect on cells
13
Osmotic pressure
14
Facilitated diffusion
15
Active transport
16
Sodium potassium pump Most used pump in animals! ATP is used to do it.
17
Types of Endocytosis phagocytosis pinocytosis
18
Exocytosis
