1 7.3 Cell Transport p208 Passive Transport- Mvt. Of materials across cell membrane without energy. Type is: Diffusion-high to low Equilibrium-equal

2 Another type: Facilitated Diffusion-molecules pass through protein channels.

3 Osmosis-diffusion water semi-permeable membrane.
Aquaporins-water channel proteins. How Osmosis Works Isotonic-same Hypertonic-above Hypotonic-below Osmotic Pressure-pressure that must be applied to prevent osmotic mvt. across membrane.

4 A: Active Transport-mvt. across membrane that requires energy
Type: Molecular Transport-mvt. using protein pump.

5 Type=Bulk Transport Endocytosis-in Phagocytosis-food in Pinocytosis-liquid in Exocytosis-out

Homeostasis refers to the necessity of an organism to maintain constant or stable conditions. In order to maintain homeostasis, all organisms have processes.

Cell Membrane Transport Notes

Cell Membrane Transport Notes
Cell Transport Osmosis and Diffusion.  Particles in constant motion  Run into each other and randomly spread out  Particles move from an area of high.
