In accomplishing facilitated diffusion in living cells:
Group of answer choices
no ATP is required
move particles down a concentration gradient
move large or impermeable particles
move particles using integral proteins
all of these
Homework Answers
The answer is all of these.
explanation
In both normal diffusion & facilitated diffusion, the particles move down the concentration gradient. Facilitated diffusion is a passive transport (no need of energy) of particles through special transmembrane integral proteins (note that carrier proteins are integral proteins). In facilitated diffusion, the molecules usually transported are glucose, ions of sodium & chloride etc. These particles are impermeable to the lipid bilayer of the plasma membrane.
hope the answer helps.

Diffusion Is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across a space. Facilitated transport Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific transmembrane integral proteins.
