How are newly made lipids supplied to the plasma membrane? Choose one: via secretory vesicles produced by the regulated exocytosis pathway via lysosomes via vesicles that bud from the ER and fuse with the plasma membrane via the constitutive pathway of exocytosis via enzymes that synthesize phospholipids, which are attached to the plasma membrane

How are newly synthesized lipids transported from the ER to the plasma membrane? Which protein is involved in this process? What protein ensures that the plasma membrane is asymmetric? Which phospholipids are specifically targeted?
Alexander B.
How do membrane phospholipids move from where they are synthesized to the membrane of lysosomes? They don't. Bound ribosomes in the lysosome membrane synthesize the phospholipids in place They are trafficked directly through the cytosol independent of vesicles They are trafficked inside the membranes of vesicles They are trafficked inside of vesicles (in the lumen)
