Osmosis is when a solvent moves from a lower concentration to a higher concentration. Facilitated diffusion is when a solvent moves down the concentration gradient through carrier molecules.

What is the difference between diffusion and facilitate diffusion?

The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.

What is the basic difference between simple diffusion and facilitated diffusion across a cell membrane?

The basic difference between simple diffusion and facilitated diffusion lies in the mechanism of transport. Simple diffusion involves the movement of small, nonpolar molecules directly across the lipid bilayer of the cell membrane without the need for protein assistance, driven by a concentration gradient. In contrast, facilitated diffusion requires specific transport proteins, such as channels or carriers, to help larger or polar molecules cross the membrane, also following a concentration gradient. Both processes are passive and do not require energy.

Compare and contrast diffusion and facilitated diffusion?

They both require a trans membrane protein. Facilitated diffusion does not require energy whereas active transport requires energy. Facilitated diffusion takes place when there is a net movement of molecules from a region of high concentration to a region of low concentration whereas active transport takes place when there is a net movement of molecules from a region of low concentration to a region of high concentration.

What are the differences between diffusion facilitated diffusion and osmosis?

Diffusion is the movement of molecules from an area of high concentration to low concentration. Facilitated diffusion involves the use of transport proteins to move specific molecules across the cell membrane. Osmosis specifically refers to the movement of water molecules across a selectively permeable membrane.


What is the difference between facilitated diffusion and simple diffusion in terms of the mechanisms by which molecules move across a cell membrane?

Facilitated diffusion involves the movement of molecules across a cell membrane with the help of specific proteins, while simple diffusion does not require any proteins and relies on the molecules moving freely through the membrane.


What is the difference between passive diffusion and facilitated diffusion?

Passive diffusion is the movement of molecules across a cell membrane from an area of high concentration to low concentration without the need for a protein carrier. Facilitated diffusion, on the other hand, requires the presence of specific protein channels or carriers to help molecules move across the membrane.

What is one similarity shared by osmosis and facilitated diffusion?

One similarity between osmosis and facilitated diffusion is that both involve the movement of molecules across a membrane from an area of high concentration to an area of low concentration, driven by a concentration gradient.
