Functionality of Golgi Apparatus

Eukarotic cells contain complex membraneous organelles known as the Golgi apparatus or Golgi body which occupy a central position in the transport system of the cell. There is a wealth of information indicating that the Golgi is a key element in biomineralization. It is, for this reason, that we will look more closely into its functionality. 

The Golgi complex is in a constant state of flux279. Cisternal membranes arising from the rough endoplasmic reticulum change to smooth endoplasmic reticulum and become the Golgi cisternae. Those cisternae then break down to vesicles which can fuse with and extend the plasmalemma. 

At one surface the Golgi apparatus has a fresh face and at the opposite surface a mature face. Membranes at the fresh face resemble those of the endoplasmic reticulum, and membranes at the mature or secreting face are similar to the plasmalemma. This suggests that the Golgi apparatus operates as a membrane transformer from endoplasmic reticulum - vesicles - Golgi apparatus - vesicles - plasmalemma. 

This suggests that the vesicle itself also has a dorsoventral asymmetry. 

High sugar concentrations have also been reported from the skeletal parts of some corals.
