Question

Why is the phospholipid molecule so appropriate as the primary structural component of plasma membrane:-
(A) Phospholipids are completely insoluble in
water
(B) Phospholipid forms strong chemical
bonds between the molecules joining a
stable structure
(C) Phospholipid form a selectively
permeable structure
(D) Phospholipid form chemical bonds with
membrane protein that keep the protein
within the membrane​

Answer 1

If saturated fatty acids are compressed by decreasing temperatures, they press in on each other, making a dense and fairly rigid membrane. If unsaturated fatty acids are compressed, the “kinks” in their tails push adjacent phospholipid molecules away, which helps maintain fluidity in the membrane

The phospholipid bilayer is a double layer of lipids which form into membranes. phospholipids have a polar head and a nonpolar tail. The watery environment outside of cells causes the tails to turn in towards each other, forming a double layer. ... The cell membrane contains channels and pumps which help in transport

Cell membranes are made up of a double layer of these phospholipid molecules. This is because in water the hydrophilic heads will face the water while the hydrophobic tails will be in the center because they face away from the water. The phospholipid bilayer makes the membrane very stable but also allows flexibility.

The lipid bilayer (or phospholipid bilayer) is a thin polar membrane made of two layers of lipid molecules. ... Biological bilayers are usually composed of amphiphilic phospholipids that have a hydrophilic phosphate head and a hydrophobic tail consisting of two fatty acid chains

Answer 2

C) phospholipid forms a selectively permeable structure is the answer
