FACILITATED DIFFUSION MOVEMENT OF MATERIALS THROUGH THE CELL MEMBRANE DIFFUSION OSMOSIS ACTIVE TRANSPORT FACILITATED DIFFUSION
DIFFUSION MOVEMENT OF MATERIALS FROM AREA OF ________ CONCENTRATION TO AREA OF ________ CONCENTRATION UNTIL __________ IS REACHED ____________________ USE ENERGY higher lower equilibrium Does not
DIFFUSION STUFF GOES FROM WHERE THERE IS _______________ TO WHERE THERE IS __________ UNTIL THERE IS _______________ AMOUNT OF STUFF More stuff less stuff an equal
WHAT SHOULD HAPPEN HERE? WHY?
Only the small molecules can pass thru the membrane
OSMOSIS MOVEMENT OF ___________ FROM AREA OF ___________ CONCENTRATION TO AREA OF ____________ CONCENTRATION UNTIL ____________ IS REACHED ________________ REQUIRE ENERGY water higher lower equilibrium Does not
WHAT SHOULD HAPPEN HERE? WHY?
Only the small molecules can pass thru the membrane
HYPOTONIC SOLUTION Where the concentration of water is __________ outside than inside Causes the water to move _______ the cell Cell will eventually _________ higher inside burst
HYPERTONIC SOLUTION Where the concentration of water is __________ outside than inside Causes the water to move _______ the cell Cell will eventually _________ lower outside shrivel
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
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
WHAT SHOULD HAPPEN HERE? WHY?
Both the large and the small molecules can pass thru the membrane
ACTIVE TRANSPORT MOVEMENT OF MATERIALS FROM AREA OF ___________ CONCENTRATION TO AREA OF _____________ CONCENTRATION _______________ REQUIRE ENERGY ASSISTED BY ________________ MOLECULES lower higher does carrier
WHAT SHOULD HAPPEN HERE? WHY?
Pinocytosis Liquid particle When a ______________ is surrounded by a pocket in the cell membrane and taken into the cell
Phagocytosis solid particle When a _______________ is surrounded by a pocket in the cell membrane and taken into the cell
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?
