Facilitated 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.

Cells take in oxygen by simple diffusion and glucose by facilitated diffusion Therefore oxygen uptake and glucose uptake will differ from each other in all respects except what?

Oxygen uptake and glucose uptake will differ in terms of the transport mechanisms involved, as oxygen is taken in by simple diffusion while glucose requires facilitated diffusion. Other factors such as energy requirements, concentration gradients, and specific transport proteins involved may also vary between the two processes.


In what ways are active transport and facilitated diffusion similar?

Active transport and facilitated diffusion are similar in that they both involve the movement of molecules across a cell membrane, but they differ in that active transport requires energy input from the cell, while facilitated diffusion does not.


How does passive diffusion differ from facilitated diffusion in terms of their mechanisms of transport?

Passive diffusion and facilitated diffusion both involve the movement of molecules across a cell membrane, but they differ in their mechanisms of transport. Passive diffusion does not require the assistance of transport proteins and relies on the natural movement of molecules from an area of high concentration to an area of low concentration. Facilitated diffusion, on the other hand, involves the use of specific transport proteins to help molecules move across the membrane, typically from an area of high concentration to an area of low concentration. In summary, passive diffusion is a simple process driven by concentration gradients, while facilitated diffusion involves the assistance of transport proteins for more efficient movement of molecules.


How does faciliated diffusion differ from simple diffusion?

Facilitated diffusion needs some sort of help. Often it would be a protein. Simple diffusion doesn't. If you spill something smelly on the floor in the kitchen, you will smell it all through the house. It will spread by simple diffusion.


What are the three forms of passive transport and how do they differ in their mechanisms of movement across the cell membrane?

The three forms of passive transport are diffusion, facilitated diffusion, and osmosis. Diffusion involves the movement of molecules from an area of high concentration to an area of low concentration. Facilitated diffusion uses protein channels to help molecules move across the membrane. Osmosis is the movement of water molecules across a selectively permeable membrane.

Is Facilited diffusion is an example of passive transport?

Yes, facilitated diffusion is an example of passive transport. The cell does not expend any energy; integral proteins in the cell's surface membrane act as carriers.

How do diffusion and osmosis differ from one another?

Diffusion and osmosis differ because diffusion is the process by which molecules spread out, or move from areas with high concentration to low concentration, and osmosis is the diffusion of water. Osmosis is a type of diffusion relating to water. It is usually used to describe the diffusion of water across a membrane (such as the cell membrane). Osmosis is also defined as the flow of solvent from a region of higher pressure toward a region of low pressure.


How does the bulk flow of filtrate into the capsule differ from diffusion?

The bulk flow of filtrate is a type of diffusion. Diffusion is a broad category of distribution of a substance within another substance. Diffusion can be specific or general in location and rate of flow.


What statements tells how facilitated diffusion differ from simple diffusion?

Particles move through cell membranes w/out the use of energy by cells.


How do diffusion of gases differ in day time and night time in plants?

It is because at day time the plants release oxygen but a night time they release carbon dioxide .

What is facilited diffusion?

Facilitated Diffusion is the movement of molecules across cell membranes through protein channels and carrier proteins.Facilitated diffusion is a passive transport process, aka no energy required, where substances move down their concentration gradient (high concentration to low concentration) across a protein through a membrane protein because it is unable to diffuse directly through the phospholipid portion of the membrane itself.Diffusion of molecules assisted by protein channels that pierce a cell membrane

Is the rate of filtration the same in all types of capillaries?

No. There are essentially three different capillaries that differ in the rate of diffusion.


How does an iron ball and water differ with respect to their shape size compressibility and diffusion?

How do osmosis differ from diffusion?

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. Osmosis is a specific type of diffusion that involves the movement of water molecules across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
