Bulgy Golgi Apparatus!!

What Is It?

The Golgi Apparatus works as an assembly line where membrane proteins go through extensive post-translational modification. Many Golgi reactions involve the addition of sugar residues to membrane proteins and secreted proteins. The carbohydrates that the Golgi attaches to membrane proteins are often quite complicated and their synthesis requires many steps.


The Golgi complex gathers simple molecules and combines them to make molecules that are more complex. It then takes those big molecules, packages them in vesicles, and either stores them for later use or sends them out of the cell. It is also the organelle that builds lysosomes (cell digestion machines). Golgi complexes in the plant may also create complex sugars and send them off in secretory vesicles. The vesicles are created in the same way the ER does it. The vesicles are pinched off the membranes and float through the cell.

What Is It Made Up Of?

The Golgi Apparatus is made up of membrane covered sacs called cisternae. It is found near the nucleus.

Interesting Facts!

  • The Golgi Apparatus was named after an Italian biologist named Camillo Golgi.

  • The Golgi apparatus has 3 names. The Golgi apparatus, the Golgi complex, and the Golgi body.
