Review on Mechanism of Facilitated Transport on Liquid Membranes
Membrane processes are used in various felds such as the environment, agriculture and different industrial sectors. These clean techniques are often adopted for directed processes such as treatment, recovery, valorization and separation. In this review article, the theoretical principles and the different classifcations of liquid membranes, such as supported liquid membra...
متن کاملEntropy facilitated active transport
We show how active transport of ions can be interpreted as an entropy facilitated process. In this interpretation, the pore geometry through which substrates are transported can give rise to a driving force. This gives a direct link between the geometry and the changes in Gibbs energy required. Quantifying the size of this effect for several proteins we find that the entropic contribution from ...
متن کاملFacilitated Transport Membrane Systems
R. D. Noble, a research profissor in chemical engineering at the Univ. of Colorado, specializes in the use of reversible chemical reactions in chemical gas and liquid separation processes, most notably the use of ion-exchange membranes as supports for complexing agents and the modeling and analysis of various facilitated transport systems. Refore joining the Univ, of Colorado, he served as an a...
متن کاملNucleocytoplasmic transport: Diffusion channel or phase transition?
How exactly large molecules translocate through nuclear pores has been mysterious for a long time. Recent kinetic measurements of transport rates through the pore have led to a novel translocation model that elegantly combines selectivity with very high transport rates.
متن کاملFacilitated diffusion on confined DNA.
In living cells, proteins combine three-dimensional bulk diffusion and one-dimensional sliding along the DNA to reach a target faster. This process is known as facilitated diffusion and we investigate its dynamics in the physiologically relevant case of confined DNA. The confining geometry and DNA elasticity are key parameters: We find that facilitated diffusion is most efficient inside an isot...
