The process described is receptor-mediated endocytosis. This is a mode of endocytosis in which specific molecules are ingested into the cell. The specificity results from a receptor-ligand interaction. Here's a step-by-step breakdown:

1. The specific molecule, or ligand, binds to its corresponding receptor on the cell surface.
2. The plasma membrane then invaginates, or folds in, around the receptor-ligand complex.
3. This invagination forms a vesicle containing the ligand and its receptor.
4. The vesicle is then pinched off from the plasma membrane and moves into the cell.
5. Once
