Carriers are like channels, are specific to a particular type of solution and can transport substances across the membrane in either direction. 2011-06-27 · Active transport and facilitated diffusion are two mechanisms that facilitate the uptake of nutrients in and out of the cells. Carrier proteins and channel proteins involve in these two processes. Also, both processes occur via the cell membrane. Facilitated transport is a type of passive transport. Unlike simple diffusion where materials pass through a membrane without the help of proteins, in facilitated transport, also called facilitated diffusion, materials diffuse across the plasma membrane with the help of membrane proteins.

Colloid-facilitated transport designates a transport process by which colloidal particles serve as transport vector of diverse contaminants in the surface water (sea water, lakes, rivers, fresh water bodies) and in underground water circulating in fissured rocks (limestone, sandstone, granite,).The transport of colloidal particles in surface soils and in the ground can also occur
Facilitated transport or diffusion or passive-mediated transport can be defined as the process of spontaneous passive transport of molecules or ions across a cell membrane through the specific transmembrane integral proteins. It does not require the ATP molecules and is the diffusion is downhill. So, the correct answer is 'c and d only'. Passive transport - The substances cross the membrane from an area of high concentration to an area of low concentration (move with the concentration gradient, or difference), without any expenditure of energy (ATP) by the cell.

The purpose of this study is to derive an approximate analytical solution for the prediction of the facilitation factor and permeation rate through liquid membranes for the facilitated transport of C[O.sub.2] where the reaction rate for C[O.sub.2] is expressed by the zwitterions reaction mechanism of Danckwerts (1979) and over a range from the moderate chemical reaction rate region to the Synonyms for Facilitated transport in Free Thesaurus.
