Vesicles are not recycled, i’m afraid. But the endoplasmic reticulum formes membrane lipids and proteins constantly. Interesting to know, the enzymes it formes are only put on the outer membrane, so without flipases the membranes would lose it’s integrity. This as a counter argument for the people who say "flip-flop is rare so we don’t have to learn about it"
where they are 2 totally different things. The cytoskeleton gives the shape it’s shape and contributes to mobility.
Flip-flop is the movement of lipids from one side of the bilayer to the other. It requires ATP and it is catalysed by enzymes known as flipases or phospholipid translocases. It occurs about once a month – very rare. i’m sorry i have no time to explain it further.
