Facilitated diffusion is the movement of molecules through those channels. (8 votes) See 1 more reply Facilitated diffusion is very similar to passive diffusion with the difference that transfer across membranes is assisted by the participation of carrier proteins embedded in the membrane bilayer. Again, the direction of passage will be from the side of the membrane with high concentration of a chemical to the side with low concentration; this also occurs without energy expenditure by the cell. 2011-06-27 · Facilitated diffusion or passive diffusion is the process that facilitates the uptake of nutrients across the cell membrane without utilizing energy. It uses trans-membrane proteins to transport nutrients into the cell. Since it involves integral proteins that are either carrier or channel protein, it differs from the simple diffusion process. Passive diffusion sampling of gaseous compounds involves diffusive transport into the device upon which the analyte either reacts with or is trapped by the sorbent medium, which may be an impregnated filter or molecular sieve.

Factors Affecting The Rate of Diffusion : The rate of facilitated diffusion depends on the kinetics of carrier-mediated transport. The rate of simple diffusion depends on the membrane permeability, size of molecules and the concentration gradient across the membrane. Kind Of Process: Facilitated diffusion can be active or a passive process. Comparing Facilitated Diffusion and Active Transport. This process is called passive transport or facilitated diffusion, and does not require energy. The solute can move "uphill," from regions of lower to higher concentration.

Simple diffusion is a passive transport as thus, doesn’t require any energy. Facilitated diffusion is also a passive transport mechanism that doesn’t require any energy, but some facilitated diffusion processes can be active. Speed. 2017-06-16 · Simple diffusion and facilitated diffusion are two passive transport methods that carry molecules across the cell membrane. Both simple and facilitated diffusion occur through a concentration gradient.
