Download file to see previous pages The movement of material across the dialysis membrane was depended on the concentration of the materials across the membrane. Notably, highly concentrated solutions were expected to move from high to low concentrations through diffusion process. Additionally, materials were also expected to move form regions of low concentration to high concentration across the membrane (movement of the experimental material out of the membrane) through osmosis process. Finally, at a certain point or zero concentration gradient no movement of materials across the cell was expected.
The concentration of any given solution determines the movement of materials across any semi or permeable membrane. The movement of water molecules or materials from regions of high concentration to regions of low concentrated refers to diffusion of materials. The materials are expected move from regions of low concentration to regions of high concentration in a process termed as osmosis. These movements are attempts of creating balance or equilibrium in concentration within the regions around any given cell membrane. Therefore, when the concentrations between the membranes are of equal concentration, there shall be no movement of material across the membrane. Hence, this process well explains different types of movements of materials across cell membranes of living organisms (Beckett ...Download file to see next pagesRead More
