The most essential difference is that one is active (uses energy) and one is passive (doesn't require energy). Take note whenever you see the word 'active' in this context- it denotes that energy is required for it to occur, usually against the concentration gradient. Facilitated diffusion is just another passive process by which molecules move from an area of high concentration to low concentration. Note that this requires no energy to occur, except it differs from diffusion in that a carrier molecule is required (usually because the molecule is too large to freely cross the plasma membrane)
Facilitated diffusion occurs when a membrane protein binds to a molecule on one side of the cell membrane and then releases it on the other side. This type of transport does not require energy and relies on the concentration gradient to move molecules across the membrane.
Yes, facilitated diffusion is reversible because it involves the movement of molecules across a membrane with the help of transport proteins. These transport proteins can facilitate the movement of molecules in both directions depending on the concentration gradient of the specific molecule.
Passive transport. It relies on the natural movement of molecules from an area of higher concentration to an area of lower concentration, following the concentration gradient. Examples include diffusion and facilitated diffusion.
In the facilitated diffusion the transport protein is needed as well in the active transport.
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.
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.

Facilitated diffusion involves the transport of molecules across the cell membrane with the help of transport proteins. These transport proteins are typically made up of proteins, which are macromolecules. Therefore, macromolecules involved in facilitated diffusion are proteins.
Facilitated diffusion occurs when a membrane protein binds to a molecule on one side of the cell membrane and then releases it on the other side. This type of transport does not require energy and relies on the concentration gradient to move molecules across the membrane.
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.

The three major processes of nutrient absorption requiring a carrier molecule for transport are facilitated diffusion, active transport, and cotransport (symport). These processes are essential for the absorption of nutrients such as glucose, amino acids, and ions in the small intestine. The carrier molecules help transport these nutrients across the cell membrane.
