| What is the Golgi Apparatus? |
| The golgi apparatus is the organelle in the cell that is important for modyfiying proteins. Under a microscope, the GA looks like numerous sacs stacked one on top of the other. The original site that proteins are made are in the ribosomes. From there they travel along the Endoplasmic Reticulum to the golgi apparatus, one of the many places the ER goes. The GA's job is to chemically modify the proteins and ship them off. |
| How? |
| The golgi apparatus has several ways on how it modifies the proteins it receives. |
| Glycosylation - the proccess of adding sugar molecules onto a protein |
| Exocytosis - the Golgi apparatus discharges some of its contents (digestive enzymes) outside the cell. |
| After modifying the proteins, the GA packages them into sacs called vessicles, specifically transitional vessicles. From there, the vessicles go to a variety of places where they are needed, such as the plasma membrane. Some vessicles end up in lysosomes, organelles that digest old material and worn out organelles |
