what is facilitated diffusion and how is it differnet than active transport and passive transport?

Question

I NEED HELP!

Answer 1

Facilitated diffusion does not consume any energy, but it does require the use of a canal or protein to transport the substrate across the membrane. Active transport also requires a protien embedded in the membrane for transportaion, but it requires energy. Passive transport does not require a protein or energy.

Answer 2

Faciliated diffusion is a process of diffusion and a form of passive transport where material crosses a membrane with the help of transport protiens
Its different then active transport since on energy is used.

Answer 3

facilitated diffusion is passive transport in the way that it doesnt use atp or energy. what it does is pinch a bit of its self off when rsending a facilitated diffused package or absorbs a vacuole (i think thats what its called) that another cell sent through facilitated diffusion

Answer 4

passivie transport: chemical or solute is transported down it's concentration gradient (from higher to lower concentration) without the expenditure of energy.

facilitated diffusion: a chemical/solute binds to a carrier which in turn, piggybacks it across the membrane

active transport: energy (ATP) is expended to pump a chemical across the membrane against its concentration gradient. An example of this is active transport of sodium and potassium in cells.
