1 Cellular Physiology TRANSPORT

2 Passive Membrane Process
Movement of molecules without energy. (no energy involves)

3 A. Diffusion The movement of molecules from a higher concentration to a lower concentration. (no energy involved)

4

5 B. Facilitated Diffusion
High → Low Diffusion helped by a carrier molecule No Energy For Big stuff like glucose

6

7 C. Osmosis The movement of water from a high concentration to a lower concentration through a membrane.

8 Osmosis 1. Hypertonic: More strength of solute outside of Cell. Higher concentration of water inside the cell then outside. Water moves outside the cell, causing the cell to shrink.

9

10 Osmosis 2. Hypotonic: Less strength of solute outside the cell. There’s a higher concentration outside the cell then inside, so water moves into the cell causing it to swell.

11

12 3. Isotonic: Equal strength of solute and water outside & inside of cell.

13

14

15 Quiz yourself

16 D. Filtration Water + molecules = forced across membrane because of pressure.
