What is simple diffusion?
Simple diffusion is the movement of particles from
high
to
low
concentration down the concentration gradient.
What factors affect the rate of simple diffusion?
The rate is affected by
temperature
, size of molecules, and
steepness
of the gradient.
What is
facilitated diffusion
?
Facilitated diffusion
is the movement of particles from high to low concentration using a
channel protein.
What is osmosis?
Osmosis is the movement of
water
from low solute concentration to high solute concentration through a
semipermeable
membrane.
What is active transport?
Active transport is the movement of particles up a
concentration gradient
, requiring ATP and a
protein carrier.
