Biology 2.1.5 Breaking down membranes

The two things that break down membranes are [blank_start]temperature[blank_end] and [blank_start]organic[blank_end] [blank_start]solvents[blank_end]

An increase in temperature results in more [blank_start]kinetic[blank_end] [blank_start]energy[blank_end]. An increase in movement results in more [blank_start]fluidity[blank_end] and permeability

The phospholipids [blank_start]vibrate[blank_end], causing them to get further apart. Once there are bigger gaps in the membrane, larger molecules can pass through

Very high temperatures completly break down the membrane

[blank_start]Ethanol[blank_end] is an organic solvent

Ethanol dissolves the [blank_start]lipids[blank_end] in the membrane as it is [blank_start]less[blank_end] polar than water, making the membrane lose its [blank_start]structure[blank_end]
