SSC MTS EXAM

Detailed explanation-1: -Cholesterol is also a key determinant of membrane fluidity: at high temperatures, cholesterol acts to stabilize the cell membrane and increase its melting point; while at low temperatures, it inserts into phospholipids and prevents them from interfering with each other to avoid aggregation [39].

Detailed explanation-2: -The membrane skeleton strengthens the lipid bilayer and endows the membrane with the durability and flexibility to survive in the circulation.

Detailed explanation-3: -The most abundant membrane lipids are the phospholipids. These have a polar head group and two hydrophobic hydrocarbon tails. The tails are usually fatty acids, and they can differ in length (they normally contain between 14 and 24 carbon atoms).
