In active transport, the molecules are carried against the force of diffusion. This is the opposite of facilitated transport. Also in active transport, energy in the form of ATP is required, since the molecules move against the normal flow. Note that energy is not needed in facilitated transport.

*Active transport: Transport of molecules AGAINST the concentration gradient with the use of a PROTEIN CARRIER. This uses ATP.
Facilitated transport: Moving of molecules through a semi permeable membrane witht he use of the cell's "facility's" AKA Protein carriers or Channels.

∙ 9y agoFacilitated diffusion and active transport differ because facilitated diffusion does not use energy. Active transport requires energy for it to work. So facilitated diffusion is more like passive transport.

∙ 10y agoIn facilitated diffusion the substance move from higher concentration to lower concentration. In this transfer it is helped by the carrier molecule. For example absorption of glucose in the intestine and transfer of amino acids in the brain. In active transport the substance is transferred against the concentration gradient. For this essentially, the energy is required. For example absorption of amino acids across the wall of small intestine and absorption of levodopa in small intestine.

How do the roles of protein molecules in diffusion differ and active transport?

How does active transport differ from diffusion?
Active transport expends energy, unlike osmosis and diffusion. Active transport is a way to move substances against concentration gradients in the cell membrane, so they need more energy to do so.
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.
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.
How are facilitated diffusion and active transport similar ad how do the differ?
both these processes do the transport against the concentration gradient uh no facilitated diffusion doesnt go against the gradient, the similiarity is that they both use carrier protiens
How can active transport differ from passive transport?
Active transport can occur against a diffusion gradient ("uphill flow).

How do diffusion osmosis facilitated diffusion and active transport diffusion differ?
Diffusion is the movement of molecules from an area of greater concentration to an area of lesser concentration. e.g. Exchange of gases in the lungs or body tissues. Osmosis is the diffusion of water through a semi-permeable membrane from an area of low solute to an area of high solute concentration. Faciliated diffusion is the passive transport of molecules down a concentration gradient. It is simply diffusion that involves a protein to make diffusion happen more easily across a cell membrane. Active transport is the moving of substances across the cell membrane using the cell's energy. Molecules are moved against a concentration gradient, i.e they move from an area of lesser concentration to an area of greater concentration. Tlhis is done by a carrier molecules which gets its energy from ATP.

How does active transport differ from passive transport-?
Active transport requires energy while passive transport does not.
How do facilitaed diffusion and active transport differ?
I'm not going to tell you the answer, stop coming here for answers, use a textbook or something...DONT CHEAT
How does active transport differ from the process of diffusion across a membrane?
Diffusion is the process in which a certain substance achieves equal concentrations in a specific area. Diffusion across a membrane means that the substance is equally distributed between both sides of the membrane, assuming the substance can pass through that membrane (the membrane is permeable to the substance).Active transport is just that, active. It requires energy because it is usually moving substances to a place where they would not naturally move or increases the rate of their disbursing. Active transport can move molecules against a concentration gradient, whereas diffusion cannot.Simply, active transport means that energy is needed to transport the object/molecule while diffusion is a naturally occurring process dependent on the concentration gradients between the membrane.
