Membrane Transport

1. Endocytosis

1.1. Pinocytosis

1.1.1. Uptake of soluable molecules (water)

1.2. Phagocytosis

1.2.1. Uptake of particulate matter

2. Active Transport

2.1. Primary Active

2.1.1. Uses ATP directly (ions and large molecules)

2.2. Secondary Active

2.2.1. Uses ATP indirectly

2.2.1.1. Cotransport

2.2.1.1.1. All solutes transported SAME direction

2.2.1.2. Counter transport

2.2.1.2.1. Solute moves opposite directions

3. Endocytosis

3.1. Pinocytosis

3.1.1. Uptake of soluable molecules (water)

3.2. Phagocytosis

3.2.1. Uptake of particulate matter

4. Simple Diffusion

4.1. 2 solutions A & B seperated by a membrane, pressure will equalize

5. Osmosis

5.1. Osmolarity

5.1.1. A solution concentration of osmotically active particles expressed as moles per liter or milliosmoles per liter

5.2. Osmolality

5.2.1. A solution concentration of osmotically active particles expressed as osmoles (or milliosmoles) per kg of water

5.3. Osmatic pressure

5.3.1. Flow of water across a semipermiable membrane due to difference in solute concentration
