Cell Membrane
Structure: made of a phospholipid bilayer and proteins
Hydrophilic phosphate head replaces one of the three lipid tails of a triglyceride
Hydrophobic lipid tails turn toward the inside of the membrane
Proteins in the membrane serve various functions:
- Carrier proteins transport materials across the membrane.
- Channel proteins allow materials to pass in and out of the membrane.
- Cell surface markers identify the cell
- Glycoproteins are made of carbohydrates attached to proteins.
- Glycolipids are made of carbohydrates attached to lipids.
Solutions
Equilibrium: even distribution of molecules
Solution: mixture in which solute particles are evenly distributed in a solution.
Solute: substance dissolved a solvent.
Solvent: liquid in which solute is dissolved.
Passive Transport
- Requires no energy
Diffusion: random movement of molecules from a region of high concentration to low concentration.
Factors affecting rate of diffusion
- concentration
- temperature
- pressure
Increase in any of these factors increases rate of diffusion
Osmosis: random movement of water molecules from a region of high concentration to low concentration across a membrane.
Isotonic: concentration of solutes is equal.
Hypertonic: concentration of solutes is greater.
Plasmolysis: cell shrivels as it loses water.
Hypotonic: concentration of solutes is lower.
Cytolysis: animal cell bursts as water enters the cell.
Turgor pressure: increase of water pressure inside a plant cell.
Facilitated Diffusion: movement of molecules from a region of high concentration to low concentration using a helper molecule.
Example: glucose must have a protein helper (which is specific to glucose) to help it move into the cell.
