Passive transport
Movement of molecules from ______ to _______
ATP, yes or no
Towards or against concentration gradient
High to low
No ATP
Towards
Types of passive transport

Osmosis
Facilitated
Simple
High to low
No ATP
No help of transport proteins
Osmosis
movement of water
Hypotonic
more in than out
Can result in hemolysis
Hypertonic

amount entering=amount leaving
equilibrium
Facilitated
Transport proteins help
High to low
Active transport Towards or against concentration gradient ATP, yes or no Transport proteins, yes or no Types
Against
yes
yes
endocytosis and exocytosis
Endocytosis
into cell
1) plasma membrane buds inwards, trapping the material that needs to come into the cell
2) vesicle pinches off from the plasma membrane
Exocytosis
out of cell
1) a vesicle forms around the particles
2) the vesicle starts to move closer to the plasma membrane and fuses with it
3) materials are released out of the cell
Pinocytosis
cell drinking
Phagocytosis
cell eating
Diffusion in the human body
Blood diffused co2 and o2 through the lungs
Simple squamous epithelium function
secretion of serous fluid
