Cell transport involves the movement of substances across the ____________
Cell Membrane
100
Substances diffuse and transport through the cell membrane in an effort to reach ____________, or balance.
dynamic equilibrium
100
A form of diffusion that involves the movement of water across a selectively permeable cell membrane
osmosis
100
If the inside of cell contains 1% solute and the outside of the cell contains 2% solute, which direction will water move in order to reach equilibrium? What type of osmosis will be observed?
Out of the cell, hypertonic
100
If the inside of a cell is 46% water and the outside of the cell is 46% water, does osmosis occur?
yes
200
Because the cell membrane lets only certain substances move into/out of the cytoplasm we say that it is:
Selectively Permeable
200
A coffee filter is an example of what kind of permeability?
a. impermeable
b. selective permeability
c. total permeability
selective permeability
200

phospholipids
200
What would be the percentage of the water in the cell?
200
Inside of cell : 75% salt, 25%water
Outside of cell: 70% salt, 30% water
Which way does water move and what is the name of the solution ?
Into cell
hypotonic
300
What is the name for the structure of the cell membrane?
phospholipid bilayer
300
The chemical energy source that cells use during active transport

If a professional football player becomes slightly dehydrated during a game, sometimes they are treated with an intravenous saline solution. What term describes the type of solution which should be used?
ISOTONIC (normal saline)
300
Inside of cell: 90% glucose
Outside of cell: 95%glucose
In which direction does osmosis occur and what type of solution is this?
out of the cell

_______________ are areas in the cell membrane that allow larger molecules to pass through
channel proteins

_____________________ is the process of a cell releasing large molecules or waste, by pushing a vesicle through the cell membrane. 
exocytosis
500
Passive transport is generally called _______.
diffusion
500
The (polar) phospholipid heads are ___________, meaning they are attracted to water.
hydrophilic

Solutions in which the solute percentage is greater outside the cell are known as _________
hypertonic
500
__________ is the process in which a cell engulfs a large substance by wrapping the membrane around it and taking it in.
ENDOCYTOSIS (if solids: phagocytosis)
