because those that can't get through the membrane by themselves can get help. transport proteins give them a ride through the membrane. different transport proteins make it easier for certain molecules to get through the membrane without cell using energy

Energy is blank from the cell for passive transport?

Energy is not required for passive transport, as it occurs naturally due to the concentration gradient without the cell expending energy. Examples of passive transport include simple diffusion, facilitated diffusion, and osmosis.

How is facilitated diffusion diferant froma an active transport?

Facilitated diffusion is a type of passive transport which does not require the cell to expend energy.


Facilitated diffusion sentence?

Facilitated diffusion is a type of diffusion specifically for larger molecules, to help them cross a selectively permeable membrane with the help of integral proteins that act as carriers. Facilitated diffusion is a passive process, i.e. it does not need energy/ATP.


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


Why isnt cellular energy required for the passenger molecule to be carried across the cell membrane by the carrier molecule?

Because of facilitated diffusion(, which nutralizes it from a higher to a lower concentration.)
