facilitated transport

(physiology)
The transport of certain materials across a cell membrane, down a concentration gradient, assisted by enzymelike carrier proteins embedded in the membrane and without the explicit provision of energy.

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 chemical equilibrium region.
They developed a model for facilitated transport of C[O.sub.2] through an amine-containing liquid membrane.
An approximate analytical model is developed for C[O.sub.2] facilitated transport in the case where the reversible reaction (1) is occurred inside the liquid membranes.
The model agreed well with C[O.sub.2] facilitated transport experiment through liquid membranes, present and literature numerical results.
