How is facilitated diffusion similar to diffusion through ion channels?
Explanation: if transport through ion channel is done down concentration gradient (high to low concentration) then it is facilitated diffusion, and if it is done up concentration gradient (low to high concentration), then it is active transport which requires ATP.16 Nov 2015
What is the function of protein carriers in facilitating diffusion?
This use of protein carriers in active transport and facilitated diffusion confers selectivity of the phospholipid membrane as only specific carriers allow specific molecules to pass into the cell through the phospholipid membrane.
What is the process of transporting molecules across the phospholipid bilayer?
Simple diffusion, facilitated diffusion and active transport are all methods of transporting molecules across the phospholipid bilayer. They share some common characteristics which include the fact that both simple and facilitated diffusion are passive processes and therefore require no energy to take place as movement takes place down the concentration gradient of the molecules - this means that some molecules will be able to diffuse into the cell, across the phosplipid bilayer simply due to there being a lower concerntration of that molecule inside of the cell that in its ambient (external) environmment.
Can facilitated diffusion take place without transmembrane proteins?
On the other hand, while facilitated diffusion and active transport can not take place without extra mechanismssuch as transmembrane proteins which are required for facilitated diffusion.
Answer
Diffusion is when molecules move from areas of high concentration to low concentration. There’s no energy needed, and it is considered as passive transport. This includes fats, oils and water that can directly across the cell membrane.

The main difference between simple diffusion and facilitated diffusion is that simple diffusion is an unassisted type of diffusion in which a particle moves from higher to a lower concentration across a membrane whereas facilitated ...
What is the purpose of simple diffusion?
It uses natural entropy to move molecules from higher concentration to a lower concentration until the concentration becomes equalized. Hence, no ATP energy is used for the transportation of molecules.
How are small nonpolar molecules transported?
Small nonpolar molecules are transported by simple diffusion. Large and polar molecules are transported by facilitated diffusion. The net movement of molecules on either side of the cell membrane is zero at the equilibrated state.

Passive transport moves across a concentration gradient, or a gradual difference in solute concentration between two areas. Facilitated diffusion is diffusion using carrier or channel proteins in the cell membrane that assist in the movement of molecules across a concentration gradient.
What is the difference between osmosis and dialysis?
The main difference between osmosis and dialysis is that the osmosis is the movement of water across a semi-permeable membrane whereas the dialysis is the separation of excess water and smaller molecules from the blood. Moreover, both osmosis and dialysis can be performed artificially in the laboratory.
What is the movement of solvent particles across a semipermeable membrane from a dilute solution into a?
Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
