Question

Explain the effect of changing temperature on the permeability of cell membranes.

Accepted Answer

Increased temperature:Kinetic energy of phospholipids increases - they vibrate moreThis increases average phospholipid separationThis increases permeability of bilayer as there are more gapsPhospholipid bilayer may melt completelyProteins may also denature leaving gaps in membraneTherefore membrane permeability will increase
