DIFFUSION: Active and Passive Transport
What is the other name for the Cell Membrane?
• Fluid Mosaic Model
Passive Transport• Does osmosis or diffusion require energy?
• No, molecules move along a concentration gradient.
Facilitated Diffusion• Facilitated Diffusion- molecules move down a concentration gradient with the aid of special proteins.
Active Transport• Requires Energy.
• ATP (form of energy made by mitochondria).
• Moves against the concentration gradient.
Endocytosis
Transporting material into a cell by the in folding of a membrane.
2 Types of Endocytosis
• Phagocytosis- Solid particles are ingested into the cell.
• Pinocytosis – liquids taken into the cell.
Exocytosis• Moves materials out of the cell
