Question

fluidity of phospholipid bilayer is increased by 1. Saturated fatty acids tails 2. Ph 3. Unsaturated fatty acid tails 4. Cholesterol

Answer 1

Answer:

3) unsaturated fatty acid

Explanation:

If unsaturated fatty acids are compressed, the “kinks” in their tails push adjacent phospholipid molecules away, which helps maintain fluidity in the membrane. ... Cholesterol functions as a buffer, preventing lower temperatures from inhibiting fluidity and preventing higher temperatures from increasing fluidity.
