Ribosome
1st step in receptor-mediated endocytosis
A. The ligand is broken down and its products enter the
cytosol across the vesicle membrane.
B. The bound receptor migrates to a coated pit region of
the membrane surface.
C. The internalized vesicle binds to a primary lysosome.
D. The receptor is separated from the ligand and recycled
to the cell surface.
E. The coated pit forms a coated vesicle by endocytosis.
F. A ligand binds an unoccupied cell surface receptor.
F. A ligand binds an unoccupied cell surface receptor.
2nd step in receptor-mediated endocytosis
A. The ligand is broken down and its products enter the
cytosol across the vesicle membrane.
B. The bound receptor migrates to a coated pit region of
the membrane surface.

D. The receptor is separated from the ligand and recycled
to the cell surface.
E. The coated pit forms a coated vesicle by endocytosis.
F. A ligand binds an unoccupied cell surface receptor.
B. The bound receptor migrates to a coated pit region of the membrane surface.
3rd step in receptor-mediated endocytosis
