Plasma membrane is fluid structure due to presence of

Answer 1

hey mate...

here is your answer...

Plasma membrane is fluid structure due to Composed of a phospholipid bilayer.

hope it helps...

Answer 2

The fluid structure of the Plasma membrane is due to the following

Explanation:

• Phospholipid forms a part of the lipid bilayer of the cell membrane.
• Each amphiphilic phospholipid molecule is comprised of :

1. A hydrophilic phosphate group that remains exposed outside.
2. Two hydrophobic fatty acid chains that remain enclosed within the lipid bilayer away from the surface.
3. A glycerol molecule that is attached to the, phosphate group by a phosphate ester bond and to the fatty acid by an ester bond.

• The phospholipids form a bilayer that in turn forms the cell membrane.
• The phospholipid bilayer is fluid or mozaic in nature and not stiff.
• Fluidity is caused by the flexible fatty acid chains which are capable of moving due to the presence of multiple unsaturations (multiple bonds,) forming kinks in the chain.
