The movement of substances (as by diffusion) across a cell membrane without the expenditure of energy.
It is possible to disrupt the plasma membrane by using enzymes and/or detergent agents.
<h3>What is the plasma membrane?</h3>
The plasma membrane is a lipid bilayer that is mainly composed of phospholipids and cholesterol.
In laboratory conditions, it is possible to disrupt this lipid bilayer by using detergent and proteins (enzymes) that break the bonds binding phospholipids.
For example, enzymes can break down the double bonds that bind fatty acids in the lipid bilayer.
In conclusion, the plasma membrane can be break down by applying enzymes and detergents.
