Functions of endoplasmic reticulum:
1. Synthesis of steroid hormone in gonad cells.
2. Detoxification
3. Ca2+ sequesteration
4. Synthesis of protein, phospholipid and carbohydrate.
5. Protein sorting to different organelles.
6. Protein modifications such as glycosylation etc.
Golgi Bodies- Golgi bodies are first visualized by a metallic stain invented by Camillo golgi and it is made of flattend, disk like cisternae arranged in a stacked manner to give 3 distinct zones (Figure 23.5). Cis-face recieves material or vesicles from endoplasmic reticulum, medial golgi is the actual place where protein are covalently modified with the sugar. Trans golgi is the face of golgi towards plasma membrane and this site sorts vesicle for their destinated organelles or plasma membrane.
Functions of golgi bodies
1. Protein sorting
2. Protein modifications (Glycosylation)
3. Proteolysis
