Contestants Don’t Forget. . .
Although they give answers in the form of questions on the TV show, you do not need to do this. You do need to write your answers on your game board! Keep track of your score … Add points for correct answers!

Structure for $100 The cell membrane is composed of what number of layers? 4, 3, 2 or 1
Two Back to Game
Structure for $200 The cell membrane is made mostly of these two molecules
(Phospho)Lipids and Proteins Back to Game
Structure Names for $300 Name this structure.
Phospholipid Back to Game
Structure for $400 Name the pictured structure.
Phospholipid or lipid bilayer Back to Game
Structure for $500 Name the purple structure in the photo.
Transport Protein Back to Game
Function for $100 Name one function (job) of the cell membrane
1. Moves substances in or out 2. boundary from environment 3. Support & Protection Back to Game
Function for $200 A cell membrane that lets some things in and keeps others out is called
Selectively or Semipermeable Back to Game
Structure for $300 The function of the lipid bilayer made of phospholipids is to
Separate the cell’s insides from its watery environment Back to Game
Function for $400 The function of this structure in the cell membrane is to allow polar substances (like water) into and out of the cell
Transport Protein Back to Game
Function for $500 The carbohydrates attached to proteins in the cell membrane are used for
Identification and signaling Back to Game
Polar of Nonpolar for $100 water
polar Back to Game
Polar of Nonpolar for $200 Fats, oils & waxes
nonpolar Back to Game
Polar of Nonpolar for $300 Sugars, Salts and ions
polar Back to Game
Polar of Nonpolar for $400 Hydrophobic Tails of the phospholipid
nonpolar Back to Game
Polar or Nonpolar for $500 Explain why a nonpolar molecule like O or CO can pass through the cell membrane 2 2
B/C they are nonpolar and the inside of the lipid bilayer is nonpolar so the can interact (like coating something in the bubble lab) Back to Game
Passive Transport for $100 The movement of molecules from high concentration to low
diffusion Back to Game
Passive Transport for $200 The diffusion of water across a selectively permeable membrane
osmosis Back to Game
Passive Transport for $300 The diffusion of polar molecules through a transport protein
Facilitated diffusion Back to Game
Passive Transport $400 A cell does not need to use this for passive transport to occur
energy Back to Game
Passive Transport for $500 A person drinks way too much water (a couple of gallons in ten minutes) in a short time. Explain why this is dangerous on a cellular level.
Blood becomes hypotonic (less concentrated) and water flows into their cells which may cause them to burst Back to Game
Active Transport for $100 For active transport to occur, cells must use their own
energy Back to Game
Active Transport for $200 During active transport substances move (up, down) the concentration gradient
Up (from low to high) Back to Game
Active Transport for $300 Transport Proteins must do this during active transport to let substances pass
Change shape Back to Game
Active Transport for $400 When a cell membrane has a vesicle release a large substance, it is called
Exocytosis Back to Game
Active Transport for $500 Name the type of cell that uses endocytosis to destroy bacteria
White Blood Cell or Macrophage Back to Game
