WARM-UP: INSTRUCTIONS FOR PASSIVE TRANSPORT FOLDABLE: 1.FOLD THE SHEET ON YOUR DESK HOT DOG- STYLE. 2.CUT TWO SLITS ON THE FRONT FLAP TOWARDS THE FOLD IN THE CENTER, MAKING 3 PANELS (3 FLAPS) 3.Turn to pg 201

Cellular transport

IIIIIIIIIIIIIIII IIIIIIIIIIIIIIII On each topic, include: Definition and picture/illustration

1.When one area has a higher concentration than the other a ___________________ exists. 2.Molecules are moved (up or down) their concentration gradient? Movement of molecules from an area of high concentration to low concentration

Passive Transport Mechanisms (require no energy) A When a space is filled evenly it is considered to be in a state of ___________.

Since oxygen is nonpolar, by what means would it pass through the cell membrane?

Passive movement using transport proteins: 1. Channel Proteins- ions, sugar, and amino acids 2. Carrier Proteins- substances must fit in their binding site

Diffusion of water through a selectively permeable membrane *Osmosis allows cells to maintain water balance as their environment changes *As a result water moves _______ the concentration gradient

SOLUTION Solute + solvent =solution Solute=substance being dissolved Solvent=substance doing the dissolving

FLIP FOLDABLE TO THE OTHER SIDE, DIVIDE INTO 3 SECTIONS AND LABEL AS FOLLOWS: 1.HYPERTONIC 2.HYPOTONIC 3.ISOTONIC INCLUDE THE FOLLOWING ON EACH: 1.DEFINITION 2.PICTURE 3.MOVEMENT OF WATER (IN, OUT, OR THE SAME)

Hypertonic Solution Hyper (solute) =“high” concentration of solutes in the solution More solutes less water (solvent) Water moves out and cell shrinks

Hypotonic Solution Hypo (solute) =“low” concentration of solutes in the solution Less solutes more water (solvent) Water moves in and cell swells

Isotonic Solution Solutes in cell = solutes outside the cell Water moves in and out at the same rate (no net movement) A healthy cell

Found in some unicellular eukaryotes, which collect excess water inside the cell and force the water out of the cell

ACTIVE TRANSPORT FOLDABLE 1.TAKE THE UPPER RIGHT HAND CORNER OF THE SHEET OF PAPER AND FOLD IT TOWARDS THE OPPOSITE LEFT SIDE. 2.OPEN IT UP AND NOW TAKE THE UPPER LEFT HAND CORNER AND FOLD IT TOWARDS THE OPPOSITE RIGHT SIDE. CUT OFF THE EXCESS PAPER OUTSIDE OF THE SQUARE. 3.YOUR FOLDABLE SHOULD LOOK LIKE THE FOLLOWING: _ _ _ _ _ _ _ CUT

_ _ _ _ _ _ _ CUT ACTIVE TRANSPORT NA + /K + PUMP ENDOCYTOSIS EXOCYTOSIS 4. FOLD EACH CORNER TOWARDS THE CENTER AND LABEL EACH TAB AS FOLLOWS: INCLUDE A DRAWING & DESCRIPTION OF EACH

Types of Active Transport: 1.Sodium-Potassium Pump-Na+/K+ 2.Endocytosis 3.Exocytosis

Active Transport Requires energy in the form of ____________ to move substances from an area of _________ to ________ concentration.

Pumps 3 (Na+) out & 2 (K+) in from an area of low concentration to high

Endocytosis Endo= “into” Movement of large particles such as proteins and polysaccharides into the cell 1. Phagocytosis –”cellular eating” uptake of solid particles (food) 2. Pinocytosis – “cellular drinking” uptake of fluids

Exocytosis- “out of cell” Movement of large materials outside of a cell by means of a vesicle
