Simple diffusion = flow of small molecules ALONG the concentration gradient, does NOT require energy.
facilitated diffusion = flow of molecules ALONG the concentration gradient with help of CARRIER PROTIENS or CHANNELS, does NOT require energy
active transport= flow of larger or charged molecules AGAINST their concentration gradient, REQUIRES input of ENERGY in the form of ATP.)
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 transport and active transport are two ways molecules can move across a cell membrane. Facilitated transport does not require energy from the cell, while active transport does require energy in the form of ATP. Facilitated transport uses carrier proteins to help molecules move across the membrane, while active transport uses pumps to move molecules against their concentration gradient.
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.
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.

Facilitated diffusion and active transport are both ways that molecules can move across the cell membrane, but they differ in their mechanisms. Facilitated diffusion uses protein channels or carriers to help molecules move from an area of high concentration to low concentration without requiring energy. Active transport, on the other hand, uses energy to move molecules against their concentration gradient, often with the help of protein pumps.

Facilated transport does not need to use energy but active transport does.
facilitated diffusion, secondary active transport and active transport
No. Facilitated diffusion is a type of passive transport.
Facilitated transport occurs when a substance moves from an area of higher concentration to an area of lower without the aid of energy. Active transport involves additional energy as it is moving from a lower concentration into a higher concentration.
simple and facilitated diffusion don't require energy and are forms of passive transport. Active transport requires energy
The sodium potassium pump requires ATP - i.e. it is involved in active transport, not facilitated transport.

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.
Both facilitated transport and active transport require the substance that passes the membrane to pass through intermembrane proteins. However, unlike active transport, facilitated transport does not require ATP because it is not actively going against the concentration gradient.
Diffusion, facilitated diffusion, passive transport, facilitated transport (?) and active transport ... unless we are referring to viral or bacterial products.
Facilitated diffusion is a type of passive transport which does not require the cell to expend energy.
