1. Transport across Plasma Membranes

2. Transport through plasma membranes
Passive transport modalities
-Simple diffusion: transport through lipid bilayer, transport through channels, Ficks law of diffusion.
-Facilitated diffusion: by carriers
Differences in diffusion Kinetics between the previous modalities
Equivalent Concentration of particles.

3. Transport through plasma membranes
Passive transport modalities
-Osmosis: concept of osmotic pressure (Van’t Hoff’s law), Oncotic (Colloid-osmotic) pressure.Osmolarity, osmolality
Hydrostatic pressure

4. Transport through plasma membranes
Active transport modalities
- Primary active transport (ATP-ase carriers or Pumps) (functions of pumps: Na+/K+ pump, Ca++ pump, H+ pump, H+/K+ pump).
- Secondary active transport (Na+
dependent carriers) examples

5. Transport through plasma membranes
Active transport modalities
- Vesicular transport: endocytosis, phagocytosis, transcytosis, pinocytosis and exocytosis and its control in secretory cells.-
