No, there is no ATP used in facilitated diffusion, because it is a form of passive transport. It only differs from normal diffusion in that it uses transport proteins to move larger or more polar molecules across the membrane of the cell.
Yes, true.
Passive diffusion does not require energy use. Facilitated diffusion does, because this transportation uses certain proteins as carriers to move the large unsoluble lipid molecules across the membrane in favor of the gradient; from higher concentration to lower concentration; yet energy is used to 'maintain' these proteins.
No. Active diffusion is the only type of diffusion that requires energy.
Yes; as opposed to unfacilitated diffusion that occurs by itself, unaided.
No its a passive process that uses that uses the concentration gradient rather than energy.
No it does not.
no is not true
No
Osmosis does not require a cell to expand its own energy. Osmosis is a type of diffusion process for water.
diffusion
It doesn't. (answer by RRU member Cyrem)
The processes that take material into cells are osmosis and diffusion. This is usually facilitated by the selective permeable membrane of the cell.
Diffusion is the movement of molecules across a selectively permeable layer from an area of high concentration to an area of low concentration. In cells, this can happen without the use of energy from the cell. Only molecules of certain sizes and attributes can diffuse. Others may need to be facilitated or moved via active transport (using energy). See the 'Related Links' below for diagrams and pictures.
It does not require the use of the cells energy.
No. Facilitated diffusion is an example of passive transport because it does not require the cell to expend energy.
Facilitated diffusion is a type of passive transport which does not require the cell to expend energy.
Cells do not gain (or use) energy through facilitated diffusion.
Passive Transport,Facilitated Diffusion, and Simple Diffusion
facilitated diffusion
I believe it is facilitated diffusionendocytosis
facilitated diffusion
Diffusion does not require energy. Diffusion is that natural tendency of particles to move from an area of high concentration to an area of low concentratrion and therefore, it does not need energy to occur.
beceause it just does
Facilitated diffusion.
Simple and facilitated diffusion are a part of passive transport. This refers to the movement of molecules, atoms and ions across the cell membrane. In both of these processes, molecules move from areas of high concentration to areas of lower concentration because equilibrium is trying to be maintained in living organisms. Simple diffusion just happens randomly and without any aides. Facilitated diffusion uses proteins in the cell membrane to guide polar molecules and ions in and out of the membrane (always to areas of lower concentration) and DOES NOT require ENERGY.Only active diffusion requires energy.
