|
|
It increases membrane fluidity
|
|
|
It decreases membrane fluidity
|
|
|
It holds the membrane together
|
Explanation:
Detailed explanation-1: -So, the correct answer is ‘It stabilizes the cell membrane’
Detailed explanation-2: -Cholesterol acts as a bidirectional regulator of membrane fluidity because at high temperatures, it stabilizes the membrane and raises its melting point, whereas at low temperatures it intercalates between the phospholipids and prevents them from clustering together and stiffening.
Detailed explanation-3: -Cholesterol plays has a role in membrane fluidity but it’s most important function is in reducing the permeability of the cell membrane. Cholesterol helps to restrict the passage of molecules by increasing the packing of phospholipids.
