In active transport, the molecules are carried against the force of diffusion. This is the opposite of facilitated transport. Also in active transport, energy in the form of ATP is required, since the molecules move against the normal flow. Note that energy is not needed in facilitated transport.

*Active transport: Transport of molecules AGAINST the concentration gradient with the use of a PROTEIN CARRIER. This uses ATP.
Facilitated transport: Moving of molecules through a semi permeable membrane witht he use of the cell's "facility's" AKA Protein carriers or Channels.

Active transport and facilitated diffusion are similar in that they both involve the movement of molecules across a cell membrane, but they differ in that active transport requires energy input from the cell, while facilitated diffusion does not.
Facilitated diffusion needs some sort of help. Often it would be a protein. Simple diffusion doesn't. If you spill something smelly on the floor in the kitchen, you will smell it all through the house. It will spread by simple diffusion.
Active transport expends energy, unlike osmosis and diffusion. Active transport is a way to move substances against concentration gradients in the cell membrane, so they need more energy to do so.
Proteins are involved in passive diffusion as channels or carriers that facilitate the movement of molecules across a membrane based on concentration gradients. In active transport, proteins use energy to actively transport molecules against their concentration gradient, requiring ATP to drive the process.
Facilitated diffusion and active transport are both ways that substances move across the cell membrane, but they differ in their mechanisms. Facilitated diffusion uses protein channels to help substances passively move from areas of high concentration to low concentration, while active transport requires energy to move substances against their concentration gradient using protein pumps.

Active transport requires energy input to move molecules against their concentration gradient, while passive transport does not require energy and moves molecules along their concentration gradient. Active transport usually involves the use of transport proteins, such as pumps or carriers, while passive transport relies on diffusion or facilitated diffusion.

Facilitated diffusion involves the movement of molecules across a cell membrane with the help of a specific protein carrier, while active transport uses energy in the form of ATP to transport molecules against their concentration gradient. Facilitated diffusion does not require energy input, whereas active transport does.
Proteins are involved in passive diffusion as channels or carriers that facilitate the movement of molecules across a membrane based on concentration gradients. In active transport, proteins use energy to actively transport molecules against their concentration gradient, requiring ATP to drive the process.
Active transport requires energy while passive transport does not.
Diffusion is the movement of molecules from an area of greater concentration to an area of lesser concentration. e.g. Exchange of gases in the lungs or body tissues. Osmosis is the diffusion of water through a semi-permeable membrane from an area of low solute to an area of high solute concentration. Faciliated diffusion is the passive transport of molecules down a concentration gradient. It is simply diffusion that involves a protein to make diffusion happen more easily across a cell membrane. Active transport is the moving of substances across the cell membrane using the cell's energy. Molecules are moved against a concentration gradient, i.e they move from an area of lesser concentration to an area of greater concentration. Tlhis is done by a carrier molecules which gets its energy from ATP.

Facilitated diffusion uses protein channels to help substances passively move from areas of high concentration to low concentration, while active transport requires energy to move substances against their concentration gradient using protein pumps.
weener!
They both require a trans membrane protein. Facilitated diffusion does not require energy whereas active transport requires energy. Facilitated diffusion takes place when there is a net movement of molecules from a region of high concentration to a region of low concentration whereas active transport takes place when there is a net movement of molecules from a region of low concentration to a region of high concentration.
Active transport requires energy input to move molecules against their concentration gradient, from low to high concentration. Diffusion is the passive movement of molecules from high to low concentration, while osmosis is the passive movement of water across a selectively permeable membrane driven by differences in solute concentration.
