The modified proteins are then enclosed in new vesicles that bud from the surface of the Golgi apparatus.
A vesicle involved only in exocytosis is typically characterized by its membrane composition, which contains specific proteins such as SNAREs that facilitate fusion with the plasma membrane. These vesicles often carry neurotransmitters or hormones and are formed through processes like budding from the Golgi apparatus. Unlike endocytic vesicles, exocytic vesicles are primarily focused on releasing their contents to the extracellular space, playing a crucial role in cell signaling and communication. Additionally, they are usually smaller and more specialized compared to general transport vesicles.
Primary lysosomes are newly formed vesicles containing digestive enzymes, while secondary lysosomes are formed when primary lysosomes fuse with endocytic vesicles containing material to be digested. Essentially, primary lysosomes are the initial structures while secondary lysosomes are the active, digestive forms.
The Golgi complex basically processes all the nutrients that come into the cell.
Endocytosis is the process used by a cell to absorb molecules and is used by all cells in the human body. There are three different types of endocytosis: Phagocytosis, pinocytosis and receptor-mediated endocytosis.
The spelling "vesicles" refers to sacs or cysts in animal anatomy, notably the seminal vesicles that provide fluid to carry semen.

Exosomes are small membrane vesicles of endocytic origin secreted by most cell types, and are thought to play important roles in intercellular communications.
New vesicles come from the lipid membranes. In most cases, they will form naturally as a result of their properties.

Receptor internalization is the process by which cell surface expressed receptors are monoubiquitinated following ligand-induced activation, and subsequently taken up into the endocytic vesicles to the lysosome. The receptor will either be degraded or brought back to cell membrane were it is again able to interact with its ligands. Receptor internalization serves as a mechanism to downregulate receptor signaling upon agonistic ligand stimulation.
