Flashcards in Chapter 5 Deck (26):
Phospholipids and proteins that have attached carbohydrate chains
Passing molecules through the membrane
Gives a "helping hand" to channel proteins. Also changes shape
Cell recognition proteins
Glycoproteins, acts like a "bar code" that helps detect foreign particles
Shape allows specific molecule to bind to it
Cause specific reactions
Plasma membrane is...
No energy required
A way that large particles can exit or enter. Exocytosis and endocytosis
Higher to lower concentration
When net movement stops
Diffusion of WATER across semi permeable membrane
Contains a solute and a solvent
Concentration of solute are equal inside and outside of the cell
Turgor pressure, swelling. Solution has less solute than the cell.
Cell shrivels. Solution has more solute than the cell
Movement of molecules that can't pass directly through membrane
Energy is required. Molecules move against concentration.
Cell takes in substances by forming vesicles around them.
Intake of large material. Digestion occurs if vehicle fuses with lysosome.
Occurs when vesicles form around a liquid or around very small particles.
Receptor mediated Endocytosis
Molecule coming into cell that binds to specific receptor
