Cell Transport Flashcards
Its consist of phospholipid bilayer
Cell Membrane
___ Head and ____ Tail
Polar - Nonpolar
Define Diffusion
net movement of solute from high concentration to low concentration to reach equilibrium
How to increase rate of diffusion
High Temp
High Concentration Gradient
Smaller Particles
2 Process of moving particles
Active ( with ATP) and Passive
4 example of Passive Process
Simple Diffusion
Facilitated Diffusion
Osmosis
Dialysis
molecules diffuse across a semi permeable membrane
Simple diffusion
Nonpolar/Polar diffuse easily using Simple diffusion
Non Polar
What molecules use simple diffusion?
O2, CO2, Steroids, Vit D E K A
Diffusion with aid of protein transporters
Facilitated Diffusion
Facilitated Diffusion is ___ than Simple Diffusion
Faster
Insulin open gates in transporters to allow ______ of glucose
Facilitated Diffusion
movement of water from high water concentration to low concentration
Osmosis
High water concentration / Low solute
Hypotonic Solution
Low water concentration / High Solute
Hypertonic Solution
kidney reclaim 99% of water using this
Osmosis
When Semipermeable membrane allow diffusion of solvent,dissolved ions, and small molecules but blocks colloidal and large particles
Dialysis
Used in medicine to remove toxins from blood as a substitute for the kidney
Dialysis
This uses protein pumps to push substance
Active Transport
Use ATP to pump sodium out of the cell and let potassium inside
Active Transport
2 Types of Bulk Transport
Endocytosis and Exocytocis
ingesting solid/liquid molecules in bulk into the cell
Endocytosis
Cell Eating
Phagocytosis
Cell Drinking
Pinocytosis
Removal of material in bull out of the cell
Exocytosis
Secretions of proteins and lipids
Exocytosis
