Which of the following enables a cell to pick up and concentrate a specific kind of molecule?
1) passive transport
2) facilitated diffusion
3) osmosis
4) receptor-mediated endocytosis
5) channel proteins

The correct answer is option 4

Receptor mediated endocytosis is an endocytotic mechanism which involves ingestion of foreign molecules into the cell. It forms a receptor-ligand interaction. The receptors bind to the targetted  ligands on the outside of the cell

Receptors on the plasma membrane of the target tissue will specifically bind to ligands on the outside of the
