Water Transport Across Cell Membranes

Jan 15 2012Water transport across cell membranes occurs by diffusion and osmosis The effective osmolality of a biological fluid is determined by the total solute concentrations and the solutes' permeabilities relative to water The cell‐membrane osmotic water permeability varies from cell to cell depending on the composition of the lipid bilayer and the presence or absence of water pores

Nov 07 2018Since water transport across the RPE is isotonic (Hamann 2002) we assume that there is no concentration jump across the epithelium and thus osmotic flux can occur only due to local osmosis through the cleft gap implying that the lateral fluxes of water and ions have the same order of magnitude as the fluxes through the cell

Transport Across Cell Membranes

Importance All cells acquire the molecules and ions they need from their surrounding extracellular fluid (ECF) There is an unceasing traffic of molecules and ions in and out of the cell through its plasma membrane Examples: glucose Na + Ca 2+ In eukaryotic cells there is also transport in and out of membrane-bound intracellular compartments such as the nucleus endoplasmic reticulum and

Cell - Cell - Transport across the membrane: The chemical structure of the cell membrane makes it remarkably flexible the ideal boundary for rapidly growing and dividing cells Yet the membrane is also a formidable barrier allowing some dissolved substances or solutes to pass while blocking others Lipid-soluble molecules and some small molecules can permeate the membrane but the lipid

Chapter 5

Water moves freely b/w cells and ECF therefore extracellular and intracellular compartments reach a state of osmotic equilibrium in which fluid concentrations are equal on the 2 sides of cell membrane Some solutes are more concentrated in one of the two body compartments than in the other meaning the body is in a state of chemical disequilibrium

Membrane permeability modeling: Kedem

The analysis of experiments for the purpose of determining cell membrane permeability parameters is often done using the Kedem-Katchalsky (KK) formalism (1958) In this formalism three parameters the hydraulic conductivity (Lp) the solute permeability (Ps) and a reflection coefficient (final sigma) are used to characterize the membrane

The Cell Membrane: Diffusion Osmosis and Active Transport

A solute is the substance dissolved in the solvent Typically a cell contains a roughly 1 percent saline solution — in other words 1 percent salt (solute) and 99 percent water (solvent) Water is a polar molecule that will not pass through the lipid bilayer however it's small enough to move through the pores — formed by protein molecules — of most cell membranes
