Solvent Concentration Effect Permeability Polar Increase Describe Cell

While water is crucial for bilayer structure, increasing concentrations of organic solvents are shown to increase cell membrane permeability.

Water, as a polar solvent, is essential for maintaining the phospholipid bilayer structure, while organic solvents, as their concentration increases, will increase the membrane's permeability.

Front Describe the effect of solvent concentration on permeability of cell membranes
Back Effect of solvent concentration on membrane permeability:
  • Water, a polar solvent is essential to maintain the phospholipid bilayer structure 
  • Organic solvents (less polar or non-polar) will increase its permeability as you increase concentration
