∙ 9y agoIt would actually just be facilitated diffusion and diffusion. Facilitated diffusion needs an ion pump or a protein channel, but diffusion doesn't need anything like that. Materials that use general diffusion can cross the cell membrane without energy or any special attention from the cell.

∙ 13y agoSimple diffusion is when particles cross the plasma membranes of cells by themselves without help from proteins or any other cellular structure. Facillitated diffusion is when praticles are transported across the plasma membrane by either active or passive transport through cellular structure.

∙ 9y agoFacilitated diffusion is a process whereby a substance passes through a membrane with a aid of an intermediary or a facilitator. The facilitator is an integral membrane protein that spans the width of the membrane. The force that drives the molecule from one side of the membrane to the other is the force of diffusion. and Diffusion is the process of movement of a substance from the region of higher concentration to the region of lower concentration so as to spread uniformly. Difference : Facilitated diffusion is when polar or charged molecules cross the cell membrane through a trans membrane channel protein. Diffusion is when small, non-polar molecules cross the cell membrane directly through the lipid bilayer. they can do so as they are hydrophobic and hence can pass through the hydrophobic core of the lipid bilayer. crossing the lipid bilayer is difficult for charged/polar particles as they are hydrophilic and large (as they may have hydration shells due to their charged nature), hence they have to cross through transport proteins.

∙ 9y agoThe main difference is that in simple diffusion molecules are brought in or out by cell membrane while in facilitated diffusion through carrier proteins (from region of higher concentration to lower concentration).

∙ 14y agoThe difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.

What is the random movement of molecules and ions down their concentration gradient called?
The random movement of molecules and ions down their concentration gradient (meaning from an area of high concentration to an area of low concentration) is called simple diffusion. Simple diffusion is related to the magnitude of driving force, permeability of the membrane, and surface area.
What is necessary for simple diffusion?
1, concentration gradient 2. diffusion constant >0
How is osmosis similar to simple diffusion?
Both affected by Concentrations?
Why does simple diffusion end?
Diffusion is complete when there ceases to be a concentration gradient. For example diffusion has ended if the concentration of a substance is equal on the inside and outside of a permeable membrane, this state is also referred to as dynamic equilibrium.
What is the difference between CaCO2 and CaCO3?
Very simple: CaCO2 is a phantasy, CaCO3 is calcium carbonate !
What is the similarity between simple diffusion and facilitated diffusion?
both need transport protein
What are the 3 types of diffusion?
simple diffusion, osmosis and facilitated diffusion.
How does facilitated diffusion from simple diffusion?
It doesn't. (answer by RRU member Cyrem)
Three types of passive transport?
There are three forms of passive transport, or the movement of biochemical and other atomic or molecular substances across the cell membranes. They are: osmosis, simple diffusion or facilitated diffusion, and filtration.
What are the types of diffusions?
In Biology there are three types of diffusion. There are simple, channel, and facilitated diffusion.
What is the transport that moves a solute down the concentration gradient?
Simple diffusion
How is active transport different than simple and facilitated diffusion?
simple and facilitated diffusion don't require energy and are forms of passive transport. Active transport requires energy
How simple diffusion can be distinguished from facilitated diffusion?
simple diffusion transports smaller molecules like oxygen and water while facilitated diffusion transports larger molecules like glucose and requires energy
What are the three transport processes that do not require cell energy?
Passive Transport,Facilitated Diffusion, and Simple Diffusion
What characteristic is shared by simple diffusion and facilitated diffusion?
They both diffuse the particles in order to reduce the boner.
How does diffusion take place in the body?
P.I.S.O.- Potassium in Sodium out facilitated diffusion, active transport , and passive transport and simple diffusion.
Two types of passive transports are?
PASSIVE TRANSPORTS ARE OF TWO TYPES. 1)SIMPLE DIFFUSION 2)FACILITATED DIFFUSION 1)SIMPLE DIFFUSION:-diffusion of water and dissolved gas is simple. when concentration on both sides of membrane becomes the same,it stops. 2)FACILITATED DIFFUSION:-this also occurs along concentration gradient with help of carrier molecules.
