Question

How is the fluidity of the cell membrane maintained?​

Answer 1

Answer:

If unsaturated fatty acids are compressed, the “kinks” in their tails push adjacent phospholipid molecules away, which helps maintain fluidity in the membrane. The ratio of saturated and unsaturated fatty acids determines the fluidity in the membrane at cold temperatures.

I hope this helps!!!!

Answer 2

Answer: The cell membrane consists of a lipid bilayer, including cholesterols that sit between phospholipids to maintain their fluidity at various temperatures.
