Receptors, in a coated pit, bind to the molecule that will enter the cell. The pit is reinforced by a lattice like network of proteins called clathrin.
Additional clathrin molecules add to the lattice, which eventually pinches off part of the membrane and forms a coated vesicle.
Inside the cell, the vesicle soon becomes uncoated as the clathrin molecules dissociate from the vesicle and each other.
The vesicle then fuses with an endosome (another vesicle) from within the cell.
The receptors are released and recycled. The receptors are returned tot he plasma membrane to bind to further complementary molecules that need to undergo receptor mediated endocytosis.
The vesicle then fuses with a lysosome which carries enzymes capable of digesting the contents of the vesicle
