Cholesterol is a structural component of cell membranes. Amount of cholesterol present can affect membrane stability and permeability. What is the role of cholesterol in a membrane?

1 A membrane that needs to be more rigid and more permeable, would have high cholesterol ratios.

2 Membranes with high amounts of cholesterol are very stable and have decreased permeability.

3 Membranes with low amounts of cholesterol are very stable and have increased permeability.

4 A membrane that needs to be rigid, such as a protective barrier, would have low cholesterol ratios.
