22 Jun 2012 It has been proposed that searching is facilitated by complementing three- dimensional diffusion with one-dimensional diffusion along DNA. Such
Facilitated diffusion definition Facilitated diffusion is the process of biological transport in which specific structural components of biological membranes interact with particular solutes or classes of solutes, markedly increasing the rates at which they can cross the membrane.
In facilitated diffusion, molecules only move with the aid of a protein in the membrane. Simple diffusion is passive but facilitated diffusion is an active process that uses energy. Simple diffusion requires molecules to move through special doorways in the cell membrane.

The presence of lipid-based membranes within a living system produces compartments that permit the selective concentration of water-soluble substances.

Facilitated diffusion. AP.BIO: ENE‑2 (EU) , ENE‑2.G (LO) , ENE‑2.G.1 (EK) Transcript. Understanding how channel proteins and carrier proteins can facilitate diffusion across a cell membrane (passive transport).
Facilitated diffusion is the passive movement of molecules along the concentration gradient. It is a selective process, i.e., the membrane allows only selective molecules and ions to pass through it.
Facilitated Diffusion. Facilitated diffusion takes place due to a difference in concentration on both sides of the membrane, in the direction of the lowest concentration, and does not require energy.
Diffusion (av latinets diffusio, av diffundere, "utbreda") är den spontana spridningsprocess som äger rum när något, oftast gaser eller vätskor, med en egenskap skilt från omgivningen sprids, blandas och jämnas ut. Ofta orsakas diffusion av något slags slumpvandring. Ett exempel på detta är när salt sprider sig jämnt i en lösning. Diffusion går fort i gaser, där molekylerna rör sig fritt och snabbt. Diffusion går långsammare i vätskor, för molekylerna där rör sig långsammare.

Passive transport occurs when molecules go down the concentration gradient. A concentration gradient is when particles or solutes move from a highly concentrated area of particles to a less concentrated area of particles.
