What is diffusion?
a difference in the concentration of a substance across a distance.
The movement of particles from places of higher density to places with lower density
The diffusion of water or other solvent from a more dilute solution to a more concentrated solution.
A state that exists when the concentration of a substance is the same throughout.
What is a concentration gradient?
A difference in the concentration of a substance across a distance.
The movement of water or another solvent from a more dilute solution to a more concentrated solution.
A state that exist when the concentration of a substance is equal throughout the cell.
The transport of substances through a cell membrane along a concentration gradient with the aid of carrier proteins.
What does Equilibrium mean?
A state that exists when the concentration of a substance is non-existent in a cell.
A state that exists when the concentration of a substance is the same throughout.
A state that exists when the concentration of a substance varies throughout
The diffusion of water or another solvent from a more dilute to a more concentrated solution.
Concentrated Diffusion
Osmosis
Diffusion
Equilibrium
Select Hypotonic, Hypertonic, and Isotonic.
HYPOTONIC
Concentration outside is higher, water diffuses out the cell
HYPERTONIC
Concentration outside is lower, water diffuses into the cell.
HYPERTONIC
Concentration outside is higher, water diffuses out the cell
ISOTONIC
Both the outside and inside have the same gradient in concentration.
HYPOTONIC
Concentration outside is lower, water diffuses into the cell.
What is facilitated diffusion?
A difference in concentration of a substance across a distance.
A state that exist when the concentration of a substance is the same throughout a space.
The transport of substances through a cell membrane along a concentration gradient with the aid of carrier proteins.
The transport of particles from regions of higher density to areas of lower density.
What are carrier proteins?
A protein that does not transport substances across the cell membrane.
A protein that transports substances into the cell from the cell membrane.
A protein that transports substances out of the cell membrane.
A protein that transports substances across the cell membrane.
