How does a vesicle form from the cell membrane?

What will be an ideal response?


When a bilayer is disrupted, it seals itself. The disruption exposes the fatty acid tails of the phospholipids to their watery surroundings. Remember, in water, phospholipids spontaneously rearrange themselves so that their nonpolar tails stay together.

A vesicle forms when a patch of membrane bulges into the cytoplasm because the hydrophobic tails of the lipids in the bilayer are repelled by the watery fluid on both sides. The fluid "pushes" the phospholipid tails together, which helps round off the bud as a vesicle, and also seals the rupture in the membrane.
