(a)
--------- is the movement of material from a region of LOW concentration to a region of HIGH concentration.
(a)
=----- has high concentration outside of the cell.
(a)
simple diffusion of water molecules are the best example.
(a)
movement of molecules from a region of high concentration to a level of low concentration with the help of a carrier protein.
(a)
– movement of material from low concentration to a region of high concentration
(a)
2 layers of phospholipids that has a phosphate group, a glycerol molecule that adhesives the polar head of the phospholipid to the ------ of the phospholipid tail.
(a)
Molecules such as --------- will go from a region of high concentration to a region of low concentration.
(a)
need to attain equilibrium
(a)
– movement of material from HIGH concentration to Low concentration w/o the use of energy.
(a)
----- must be energized thru the use of ------- to pump out of the cell the from low concentration to a higher concentration gradient.
(a)
----- Needed ATP (ADENOSINE TRIPHOSPHATE) to make it work.
(a)
CO2 and O2 are small non- polar gasses that can easily diffuse across the cellular membrane as an example of ---------.
(a)
– glucose transport across membrane with help of carrier protein.
(a)
Facilitated diffusion is a passive transport due to no -------- requirement
(a)
Requires NO energy
