What factors can affect membrane permeability? AAT Bioquest

WebAt increased raised temperatures lipids in the fatty acid chains begins to liquefy which increases the fluidity of the cell, the membrane then becomes more permeable, letting things in and out of the cell that it normally wouldn’t which will then denature (breakdown) the proteins within the cell. Also the speed increases within the cell. WebAs temperature increases, the components in the membrane gain kinetic energy and move around more. The more fluid the membrane is, the more substances it allows through. As temperatures exceed 45oC, permeability increases rapidly because proteins in the membrane become denatured and start to unravel.
