Diagram illustrating exocytosis in cell biology, showing how secretory vesicles from the Golgi apparatus fuse with the cell membrane to release proteins, with pathways for both regulated and unregulated secretion labeled.

Diagram showing receptor-mediated endocytosis in a cell: a ligand binds to a receptor on the cell membrane, forming a coated pit that becomes a coated vesicle. The vesicle fuses with an endosome, where receptors are recycled and the contents are degraded in a lysosome.

Soluble and secretory proteins leaving the Golgi apparatus undergo exocytosis

The secretion of soluble proteins occurs constitutively. In contrast, the exocytosis...
