Question

Differentiate between facilitated diffusion and active transport.

Answer 1

Hint: The transfer of material from a region of high concentration to an area of low concentration is diffusion. Diffusion occurs in liquids and gases when their particles spontaneously travel from one position to another. It is the sort of passive diffusion of solutes in the plasma membrane by transport proteins. A facilitated diffusion is a form of passive transport.

Complete answer: Difference between facilitated diffusion and active transport.

Facilitated Diffusion	Active Transport
Facilitated diffusion takes place down the gradient of concentration.	Active transport takes place toward the gradient of concentration.
Facilitated diffusion is a passive method and needs no energy.	An active method is an active transport. Thus, energy is needed.
In transportation, facilitated diffusion uses both gated channel proteins and carrier proteins.	Active transport uses proteins from the carrier. In order to adjust the shape of the carrier protein, energy is used.
For mainly big, polar molecules, facilitated diffusion is used which cannot cross the phospholipid bilayer as they are hydrophilic (polar molecules).	To transport molecules against their gradient of concentration, active transport is used.

Note: Active transport is typically associated with the collection of high molecular concentrations, such as ions, glucose and amino acids, that the cell requires. The absorption of glucose in the intestines in humans and the absorption of mineral ions into plant root hair cells are examples of the active transport. There are three primary forms of active transport: The sodium-potassium pump, exocytosis and endocytosis.
