Cell Membrane

QuestionAnswer
Cell membrane is a phospholipid bilayer that shows selective permeability for substances
Adhesion proteins help cells stick together to proper tissues
Communication proteins two cells match up and form a channel between cytoplasms and send signals
Receptor proteins takes in outside signals so a cell can change its activities, like making a protein, block a reaction, or divide
Recognition proteins identifies self vs. non-self
Transport proteins moves things in and out of cells
Membrane crossing mechanisms Diffusion across lipid bilayer, passive transport, active transport, endocytosis, exocytosis
Diffusion net movement of molecules or ions from HIGH TO LOW concentration
Passive transport HIGH TO LOW, no energy, needs transport protein, EX: simple sugars, monosaccharides, disaccharides, alcohols
Active transport LOW TO HIGH, must activate transport protein, ATP needed, EX: ions
Endocytosis eats the cell
Exocytosis brings into the cell
Osmosis movement of water molecules through HIGH TO LOW through semi permeable membrane
Tonicity solute concentration of two liquids
Hypertonic higher solute concentration and lower water concentration
Isotonic equal water and solutes
Hypotonic higher water concentration and lower solute concentration

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
