Editing Exocytosis (section)

=== Constitutive exocytosis ===
Constitutive exocytosis is a continuous process that occurs in all cells. It is involved in the addition of new membrane proteins and lipids to the plasma membrane or the extracellular area. This process does not require any additional signalling and is an important part in maintaining the cells membrane by inserting new membrane proteins. The molecular machinery in constitutive exocytosis is under continuous research and proteins such as ELKS<ref>{{cite journal |last1=Held |first1=Richard G. |last2=Kaeser |first2=Pascal S. |title=ELKS active zone proteins as multitasking scaffolds for secretion |journal=Open Biology |date=February 2018 |volume=8 |issue=2 |pages=170258 |doi=10.1098/rsob.170258 |pmid=29491150 |pmc=5830537 }}</ref> and [[Exocyst|EXOCYST]] are complexes that contribute to the tethering of vesicles to the plasma membrane. This makes sure there is a proper fusion and secretion of material.
