Froggy Jumps Cell TransportOnline version cell transport by Dr. David Myers 1 Facilitated diffusion a b c 2 simple diffusion a b c 3 endocytosis a b c 4 exocytosis a b c 5 lipid solubles pass thru by: a simple diffusion b exchange pump c facilitated diffusion 6 causes RBC to swell up and burst a hypotonic b hypertonic c isotonic 7 movement of water thru semipermeable membrane a osmosis b active transport c facilitated diffusion 8 Down the concentration gradient means: a high to low b low to high c IDK 9 Which does NOT involve movement of molecules from high concentration to lower? a endocytosis b osmosis c facilitated diffusion 10 Two types of passive transport are: a endocytosis and diffusion b diffusion and facilitated diffusion c exocytosis and osmosis 11 A patient arrives in the hospital extremely dehydrated. In order to fill his cells with fluid, he should receive a(n) _______ intravenous drip. a isotonic b hypertonic c hypotonic 12 A solution that contains fewer solutes than the cell is: a hypotonic b isotonic c hypertonic 13 Which one is NOT true about cell membranes a it allows water soluble molecules to pass through easily b it contains proteins for specialized functions c it consists of a phospholipid bilayer 14 a cell ingest bacteria. What type of transport is this? a diffusion b exocytosis c endocytosis 15 Which is not an active transport process? a exocytosis b sodium potassium pump c facilitated diffusion 16 Facilitated diffusion requires a ATP b protein channels c vacuoles 17 A cell would plump with water and possibly lyse in which solution? a hypotonic b hypertonic c isotonic 18 Diffusion occurs because: a molecules are attracted to each other b cellular energy pumps molecules across a membrane c molecules constantly move and collide 19 Diffusion of water through a selectively permeable membrane is called? a osmosis b pinocytosis c facilitated diffusion 20 An RBC surrounded by fresh water will burst because: a water will move out of the cell b solutes will move into the cell c water will move into the cell 21 Which requires energy? a diffusion b osmosis c active transport 22 Which types of molecules will easily pass through the fatty acid chains in the cell membrane? a hydrophobic b hydrophilic c polar 23 How is the phospholipid bilayer oriented? a heads face inward b Tails face each other c head and tails alternate directions 24 During diffusion molecules tend to move a the direction doesn't depend on concentration b down the concentration gradient c against the concentration gradient 25 When the concentration of a solute is the same throughout the system, it has reached______ a equilibrium b osmosis c maximum concentration 26 Phagocytosis, pinocytosis, and exocytosis are all a facilitated b passive c active 27 glucose enters a cell from high to low concentration by a facilitated diffusion b simple diffusion c osmosis 28 Which is NOT a passive transport? a sodium potassium pump b facilitated transport c osmosis 29 Placing an RBC in a hypertonic solution will cause the cell to a expand b shrivel, crenate c no change 30 Gases like oxygen and carbon dioxide move freely across a cell membrane by a diffusion b ion channels c endocytosis
