Question

Cholesterol makes the lipid bilayer more or less permeable to small molecules passing through? more or less rigid

Answer 1

Cholesterol increases the rigidity of the lipid bilayer in the cell membrane.

Step-by-step explanation:

Cholesterol provides rigidity to the cell membrane. The higher the proportion of cholesterol in the membrane, the more rigid it becomes. This rigidity reduces the fluidity of the membrane and decreases permeability to some ions.
