Cell Transport Concept Map
Passive Transport
Osmosis
Cellular Transport
Maintain Balance (Homeostasis)
Cell Membrane
Exocytosis
Phospholipids Bilayer
The phospholipids in the plasma membrane are arranged in two layers, called aphospholipid bilayer.
The phospholipids bilayer's structure contains of hydrophobic tails of phospholipid molecules are inbetween two layers of hydrophilic heads.
Simple Diffusion
No ATP/energy required
High Concentration to Low Concentration (With the flow)
Proteins
Integral
Peripheral
Cholesterol
Carbohydrates
Active Transport
Isotonic
Endocytosis
Protein Pump
Pinocytosis
Phagocytosis
Hypotonic
Hypertonic
Means of removing wastes from the cell
Used for eliminating small liquid solutes
Used for eliminating small solid substances
Energy/ATP required
Low to High Concentration (Against the flow)
Solution lower solute concentration
Solution higher solute concentration
Facilitated Diffusion
Diffusion of water across a semipermeable membrane
Tonacity
The concentration of the solution
When the solution is in equilibrium
Channeling or transporting molecules across the membrane.
The peripheral membrane proteins function in support, communication, enzymes, and molecule transfer in the cell.
At high temperatures, cholesterol acts to stabilize the cell membrane and increase its melting point; while at low temperatures, it inserts into phospholipids and prevents them from interfering with each other to avoid aggregation.
Helping cells recognize each other and providing protection for cells.
No ATP/energy required
High Concentration to Low Concentration (With the flow)
