What is diffusion?
The movement of molecules through a semi-permeable membrane from an area of lower concentration to an area of higher concentration.
The movement of molecules through a semi-permeable membrane from an area of higher concentration to an area of lower concentration.
The movement of molecules across a semi-permeable membrane until there are equal amounts on each side of the membrane.
Molecules desire to spread as far from a membrane as possible.
What is osmotic pressure?
The minimum pressure required to start osmosis.
The pressure required to cause a cell to burst.
The minimum pressure that must be applied to stop osmosis.
The pressure under the sea.
A solution with 1.5% saline in it would be considered:
(For reference, blood has 0.9% saline in it).
Hypotonic
Isotonic
Hypertonic
Water
When put into distilled water, a red blood cell will:
Inflate until it pops.
Stay the same.
Shrink (Crenate).
Double in size and then stay that way.
In reverse osmosis, the solvent passes through the membrane at a much faster rate than the dissolved solids.
True
False
In reverse osmosis, pressure that is greater than the naturally occurring osmotic pressure is applied in order to _____________
Mineralize water
Desalinate (remove salt) water
Decompose water
Push bacteria across membrane
When sugar is mixed with water, equilibrium is reached when....
Molecules of sugar stop moving.
Water and sugar molecules are moving at the same speed.
The dissolved sugar molecules are evenly distributed throughout the solution.
There are the same number of water molecules as dissolved sugar molecules.
The rate of diffusion is affected by which of the following?
a) Temperature
b) Size of molecules
c) Steepness of the concentration gradient
A and B
A, B and C
What is the difference between osmosis and simple diffusion?
There is absolutely no difference between the two.
Simple diffusion is the movement of water from an area with less concentration dissolved particles to one with higher; osmosis is the movement of molecules from an area of high concentration to low.
One requires energy to complete, the other does not.
Simple diffusion is the movement of molecules from an area of high concentration to low; osmosis is the movement of water from an area with less concentration dissolved particles to one with higher.
Simple Diffusion is able to use the concentration gradient for moving SMALL NON-POLAR molecules across the plasma membrane.
True
False
