FACILITATED DIFFUSION
MOVEMENT OF MATERIALS THROUGH THE CELL MEMBRANE DIFFUSION OSMOSIS ACTIVE TRANSPORT FACILITATED DIFFUSION
2
DIFFUSION MOVEMENT OF MATERIALS FROM AREA OF ________ CONCENTRATION TO AREA OF ________ CONCENTRATION UNTIL __________ IS REACHED ____________________ USE ENERGY higher lower equilibrium Does not
3
DIFFUSION STUFF GOES FROM WHERE THERE
IS _______________ TO WHERE THERE IS __________ UNTIL THERE IS _______________ AMOUNT OF STUFF More stuff less stuff an equal
4
WHAT SHOULD HAPPEN HERE? WHY?
5
Only the small molecules can pass thru the membrane
6
OSMOSIS MOVEMENT OF ___________ FROM AREA
OF ___________ CONCENTRATION TO AREA OF ____________ CONCENTRATION UNTIL ____________ IS REACHED ________________ REQUIRE ENERGY water higher lower equilibrium Does not
7
WHAT SHOULD HAPPEN HERE? WHY?
8
Only the small molecules can pass thru the membrane
9
HYPOTONIC SOLUTION Where the concentration of water is __________ outside than inside Causes the water to move _______ the cell Cell will eventually _________ higher inside burst
10
HYPERTONIC SOLUTION Where the concentration of water is __________ outside than inside Causes the water to move _______ the cell Cell will eventually _________ lower outside shrivel
11
ISOTONIC SOLUTION Where the concentration of water is __________ outside and inside Causes the water to move _______ the cell Cell will eventually _________ the same into and out of stay the same
12
FACILITATED DIFFUSION
Proteins create ____________ that allow certain chemicals to pass thru the cell membrane channels STUFF GOES FROM WHERE THERE IS _______________ TO WHERE THERE IS __________ UNTIL THERE IS _______________ AMOUNT OF STUFF More stuff less stuff an equal Does not ____________________ USE ENERGY
13
WHAT SHOULD HAPPEN HERE? WHY?
14
Both the large and the small molecules can pass thru the membrane
15
ACTIVE TRANSPORT MOVEMENT OF MATERIALS FROM AREA OF ___________ CONCENTRATION TO AREA OF _____________ CONCENTRATION _______________ REQUIRE ENERGY ASSISTED BY ________________ MOLECULES lower higher does carrier
16
WHAT SHOULD HAPPEN HERE? WHY?
18
Pinocytosis Liquid particle
When a ______________ is surrounded by a pocket in the cell membrane and taken into the cell
19
Phagocytosis solid particle
When a _______________ is surrounded by a pocket in the cell membrane and taken into the cell
21
Review Questions: Answer on separate paper, please.
Compare osmosis and diffusion. Contrast osmosis and diffusion. How is active transport different from both osmosis and diffusion. How is pinocytosis different from phagocytosis? How is facilitated diffusion different from normal diffusion?
