What is the difference between facilitated diffusion with help of the carrier molecule and active transport with help of a transport protein?

Answer 1

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)

Answer 2

Facilitate transport moves particles from high concentrated areas to low concentrated areas. Active transport moves particles from low concentrated areas to high concentrated areas and needs energy to do so.

Answer 3

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.

Answer 4

Facilitated diffusion is a type of passive transport in which a substance moves across the cell membrane from high to low concentration. In this situation, the substance moves with the concentration gradient, and with the help of carrier molecules, it is able to make it's way across the membrane smoothly and without the expense of energy.

Active transport, on the other hand, is the movement of a substance across the cell membrane from low to high concentration, making the transport a bit more difficult and calling for the use of energy. Transport proteins recognize the substance and allow it to cross through the membrane.

Answer 5

Facilitated diffusion doesn't require ATP, active transport does. As a result, active transport is faster than facilitated diffusion. Active transport is against the concentration gradient and involves endocytosis. Facilitated diffusion is down the concentration gradient.
