45

the dispersal of perfume in a room is an example of
The dispersal of perfume in a room is an example of
  • Diffusion
  • Osmosis
  • Active transport
  • Endocytosis

45

when an egg is placed in distilled water water will diffuse into the egg through the process of
When an egg is placed in distilled water, water will diffuse into the egg through the process of
  • Solubility
  • Osmosis
  • Selective transport
  • Endocytosis

45

cells will shrink when placed in a n
Cells will shrink when placed in a(n)
  • Hypotonic solution
  • Hypertonic solution
  • Isotonic solution
  • None of the above

45

the interior portion of a cell membrane forms a nonpolar zone that
The interior portion of a cell membrane forms a nonpolar zone that
  • Allows polar molecules to pass through the membrane
  • Allows food to pass through the membrane
  • Prevents ions and most large molecules from passing through the membrane
  • None of the above

45

proteins that act like selective passageways in the cell membrane are known as
Proteins that act like selective passageways in the cell membrane are known as
  • Marker proteins
  • Channel proteins
  • Receptor proteins
  • Enzymes

45

ions move through by
Ions move through by .
  • Receptor proteins; endocytosis
  • Marker proteins; diffusion
  • Ion channels; passive transport
  • Enzymes; active transport

45

diffusion continues until the concentrations are the same in all areas which is known
Diffusion continues until the concentrations are the same in all areas which is known
  • Active transport
  • Dynamic equilibrium
  • Passive transport
  • Exocytosis

45

this determines the direction in which a substance diffuses across a cell membrane
This determines the direction in which a substance diffuses across a cell membrane.
  • Diffusion
  • Dynamic equilibrium
  • Osmosis
  • Concentration gradient

45

proteins involved in both facilitated diffusion and active transport are
Proteins involved in both facilitated diffusion and active transport are
  • Carrier proteins
  • Receptor proteins
  • Marker proteins
  • Enzymes

45

which of the following require energy
Which of the following require energy?
  • Diffusion
  • Osmosis
  • Facilitated diffusion
  • Sodium-potassium pump

45

unlike active transport passive transport
Unlike active transport, passive transport
  • Requires no energy
  • Moves substances against their concentration gradient
  • Does not involve carrier proteins
  • All of the above

45

which of the following is a form of passive transport
Which of the following is a form of passive transport?
  • Endocytosis
  • Exocytosis
  • Ion channels
  • Sodium-potassium pumps

45

sodium potassium pumps will pump sodium ions the cell and potassium ions the cell
Sodium-potassium pumps will pump sodium ions the cell and potassium ions the cell.

slide16
Molecules that are too large to fit across the cell membrane can be transported into the cell by and out of the cell by
  • Facilitated diffusion; ion channels
  • Diffusion; osmosis
  • Channel proteins; dynamic equilibrium
  • Endocytosis; exocytosis

45

unlike facilitated diffusion active transport
Unlike facilitated diffusion, active transport
  • Moves substances against the concentration gradient
  • Uses proteins in the process
  • Moves molecules through the cell membrane
  • Requires no energy

slide18
Which cell is most likely to gain both water molecules and solute molecules as the system approaches equilibrium?
  • Cell 1
  • Cell 2
  • Cell 3
  • Cell 4

45

in this system solute molecules in cell 4 are most likely to
In this system, solute molecules in cell 4 are most likely to
  • Remain in cell 4.
  • Adhere to cell 4’s membrane
  • Diffuse into cell 3
  • Diffuse into cell 2

45

in which direction are water molecules in this system most likely to diffuse
In which direction are water molecules in this system most likely to diffuse?
  • From 1 to 2
  • From 3 to 4
  • From 4 to 2
  • From 1 to 3

45

osmosis is the diffusion of molecules across a cell membrane
Osmosis is the diffusion of molecules across a cell membrane.
  • Glucose

45

membranes are if they allow only certain substances to move across them
Membranes are if they allow only certain substances to move across them.
  • Permeable
