1. Moving across a membrane

2. 2 ways of getting through the membrane ( pg 12 )
Passive Transport and Active Transport
Passive Transport = Movement of particles from areas of high concentration to areas of low concentration.
Does not require energy
Active Transport = Movement of particles from areas of low concentration to high concentrations.
Energy required

4. Passive Transport Diffusion
Water, lipids, and lipid soluble substances (hormones and vitamins) to pass through the plasma membrane

5. Passive Transport Facilitated Diffusion
Channel proteins that provide opening which specific molecules and ions can diffuse across the membrane. Examples: sugars, amino acids, and ions

7. Active Transport Carrier proteins
Bind to specific molecules to move them from an area of low concentration to an area of high concentration

8. Active Transport Endocytosis
Large particles are engulfed by a portion of the cell membrane, the membrane then breaks off and travels into the cell with the particle

9. Active Transport Endocytosis 2 types of endocytosis
Phagocytosis : Food (aka nutrients)
Pinocytosis: Water

10. Active Transport Exocytosis
Contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane.
