Let me share with you a comparison between Forming and maturing face of Golgi apparatus.
| Aspect | Forming Face of Golgi Apparatus | Maturing Face of Golgi Apparatus |
| Location | Near the cis-Golgi network (proximal end) | Near the trans-Golgi network (distal end) |
| Structure | Stacks of cisternae are smaller and less compact | Stacks of cisternae are larger and more compact |
| Surface | Outer and convex | Inner and concave |
| Role of enzymes | Enzymes involved in glycosylation and initial modifications | Enzymes involved in final modifications and sorting |
| Vesicle Formation | Vesicles bud off to transport modified proteins to other organelles or the cell surface | Vesicles bud off for transport to the plasma membrane or lysosomes |
| Function | Initial glycosylation and addition of some functional groups | Final glycosylation, processing and sorting of proteins |
| Membrane Trafficking | Receives vesicles from the endoplasmic reticulum (ER) | Sends vesicles to various cellular destinations |
| Maturity Stage | Immature or early stage | Mature or late stage |
