1 MOVING MATERIALS INTO AND OUT OF CELLS

2 MATERIAL MOVEMENT PASSIVE TRANSPORT ACTIVE TRANSPORT

3 PASSIVE TRANSPORT DIFFUSIONOSMOSIS

4 PASSIVE TRANSPORT PARTICLES PASSING THROUGH THE CELL MEMBRANE PARTICLES PASSING THROUGH THE CELL MEMBRANE WITHOUT USING ENERGY WITHOUT USING ENERGY

5 DIFFUSION MOVEMENT FROM AN AREA OF HIGHER CONCENTRATION TO AN AREA OF LOWER CONCENTRATION MOVEMENT FROM AN AREA OF HIGHER CONCENTRATION TO AN AREA OF LOWER CONCENTRATION

6 DIFFUSION (CONTINUED)

7 WHAT IS THE SOLUTE? WHAT IS THE SOLUTE? WHAT IS THE SOLVENT? WHAT IS THE SOLVENT? WHAT IS EQUILIBRIUM? WHAT IS EQUILIBRIUM?

8 OSMOSIS MOVEMENT OF WATER ACROSS A MEMBRANE

9 OSMOSIS (CONTINUED) RESULT OF OSMOSIS IS EXTRA MOLECULES COLLECT ON ONE SIDE OF THE MEMEBRANE RESULT OF OSMOSIS IS EXTRA MOLECULES COLLECT ON ONE SIDE OF THE MEMEBRANE PRESSURE EXERTED BY WATER MOLECULES IS OSMOTIC PRESSURE PRESSURE EXERTED BY WATER MOLECULES IS OSMOTIC PRESSURE

10 OSMOSIS (CONTINUED) HYPOTONIC SOLUTION HYPOTONIC SOLUTION –WATER CONCENTRATION HIGHER IN ENVIRONMENT THAN IN CELL –WATER WILL MOVE INTO THE CELL

11 OSMOSIS (CONTINUED) HYPERTONIC SOLUTION HYPERTONIC SOLUTION –WATER CONCENTRATION LOWER IN ENVIRONMENT THAN IN CELL –WATER WILL MOVE OUT OF THE CELL

12 OSMOSIS (CONTINUED) ISOTONIC SOLUTION ISOTONIC SOLUTION –WATER CONCENTRATION SAME ON BOTH SIDES OF THE MEMBRANE –WATER MOLECULES WILL MOVE INTO THE CELL AT THE SAME RATE AS THEY MOVE OUT

13 OSMOSIS (CONTINUED) TURGID = SWOLLEN LYSED = BREAK FLACCID = NOT FIRM SHRINK

14 FACILITATED DIFFUSION MEMBRANE CONTROLS WHAT CROSSES MEMBRANE CONTROLS WHAT CROSSES MEMBRANE IS REFERRED TO AS SELECTIVELY PERMEABLE MEMBRANE IS REFERRED TO AS SELECTIVELY PERMEABLE

15 ACTIVE TRANSPORT

16 ENERGY IS USED TO MOVE MATERIAL ACROSS THE MEMBRANE ENERGY IS USED TO MOVE MATERIAL ACROSS THE MEMBRANE USUALLY FROM AREA OF LESSER CONCENTRATION TO AREA OF GREAT CONCENTRATION USUALLY FROM AREA OF LESSER CONCENTRATION TO AREA OF GREAT CONCENTRATION

17 ACTIVE TRANSPORT (CONTINUED) EXAMPLE: SODIUM- POTASSIUM PUMP EXAMPLE: SODIUM- POTASSIUM PUMP MOVEMENT GLUCOSE INTO CELL: TYPCIALLY, CONC WILL BE GREATER IN CELL MOVEMENT GLUCOSE INTO CELL: TYPCIALLY, CONC WILL BE GREATER IN CELL

18 Na + MOVED AGAINST CONCENTRATION GRADIENT

19 ENDOCYTOSIS MOVEMENT OF MATERIAL INTO THE CELL

20 EXOCYTOSIS MOVEMENT OF MATERIAL OUT OF THE CELL MOVEMENT OF MATERIAL OUT OF THE CELL html html html html
