Exocytosis is the cellular process in which intracellular vesicles in the cytoplasm fuse with the plasma membrane and release or secrete their contents into the extracellular space.Exocytosis can be constitutive (occurring all the time) or regulated.hoto by: Alila.

The formation of a transport vesicle (often called âbuddingâ) is not a spontaneous process and requires an input of energy. Eukaryotic cells have evolved a variety of protein machineries, known as coats, that are designed for this purpose.uestions. Our lab is interested in a number of unresolved issues that concern how transport vesicles are formed and consumed in a living cell. While it is known that removal of a vesicle coat must occur prior to membrane fusion, in many cases, exactly when and how vesicle coats are removed is not well understood.
