Facilitated diffusion uses integrated proteins that act as channels for ions or molecules to pass through.

Facilitated diffusion involves the use of carrier proteins to move specific molecules across the cell membrane, while simple diffusion does not require proteins and involves the movement of molecules from an area of high concentration to low concentration. Facilitated diffusion is selective and allows for faster transport of specific molecules that may be too large or polar to diffuse freely through the membrane.
Facilitated diffusion does not require the use of energy.
Diffusion is the movement of molecules from an area of high concentration to low concentration. Facilitated diffusion involves the use of transport proteins to move specific molecules across the cell membrane. Osmosis specifically refers to the movement of water molecules across a selectively permeable membrane.
No, facilitated diffusion does not require the cell to use energy. It is a passive process that relies on the concentration gradient to move molecules across the cell membrane with the help of transport proteins.
Facilitated diffusion is a type of passive transport that relies on carrier proteins to move specific molecules across the cell membrane. It does not require energy input from the cell and moves molecules down their concentration gradient. Facilitated diffusion is selective, allowing only specific molecules to cross the membrane based on their size and charge.
A large glucose molecule requires facilitated diffusion because it is too big to pass through the cell membrane without assistance from transport proteins. In contrast, an oxygen molecule is small enough to diffuse freely across the cell membrane through simple diffusion due to its size and hydrophobic nature.
