Assisted transport of a molecule across the cell membrane without an expenditure of energy is known as?
Any movement of molecules into or out of a cell without the expenditure of energy is called diffusion. If the molecule uses special channels to diffuse through the membrane (again, not expending energy), it is called facilitated diffusion.
Is osmosis an example of facilitated diffusion or active transport?
No. Facilitated diffusion is an example of passive transport because it does not require the cell to expend energy.
What requires no energy from the cell?
facilitated diffusion
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.
Do cells gain and then use energy through facilitated diffusion?
Cells do not gain (or use) energy through facilitated diffusion.
What used a protein to move a molecule across a cell membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.

What does facilitated diffusion requires?
Facilitated diffusion requires energy. This is because facilitated diffusion is the transfer of molecules from a lower concentration to a higher concentration.membrain pouch
What uses a protein to move a molecule across a membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
What requires the use of energy and help of transport proteins to move a molecule across a cell membrane?
Facilitated diffusion
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.)
Is osmosis an example of facilitated diffusion or active transport?
No. Facilitated diffusion is an example of passive transport because it does not require the cell to expend energy.
What does active transport and facilitated diffusion have in common?
Active transport is when proteins move substances into the cell while expending energy. Facilitated diffusion is the movement of chemicals through a protein into a cell.
What is the difference between facilitated diffusion with the help of a carrier molecule with the help of a transport protein?
Facilitated diffusion is a type of passive transport (does not require energy). It is called facilitated diffusion because it utilises the carrier protein to diffuse through it. Active transport requires energy to pump certain big molecules to cross over and this uses transport protein. Basically, the difference is just the usage of energy.
What requires the use of energy and the help of transport proteins to move a molecule across the cell membrane?
Facilitated diffusion
What requires no energy from the cell?
facilitated diffusion
What type of transport does a small molecule enter a cell with help from a membrane protein additional energy is needed to complete this process?
Facilitated
