- Phospholipids: These substances have a composition which is in between the structure of phospholipids of endoplasmic reticulum and plasma membrane.
- Enzymes: ATP-ase, CPT-ase, transphorases, etc. enzymes are. present.
- Carbohydrates: Glucose, manose, galactose carbohydrates are seen.
- From E R: Beams & Kessel' in 1968 proposed that Golgi system cisternae arise from Endoplasmic reticulum.
- Rough E.R. produces protein which will be transfer to smooth ER.
- Vesicles are developed from smooth E.R.
- By the fusion of vesicles cisternae are formed. From the cisternae secretory vesicles are formed on the maturing face. (These sides are called "G.E.R.L" - Golgi Endoplasmic Reticulum Lysosome)
2) From nuclear membrane: In 1965 "Bouch" described the origin of golgi from the outer membrane of the nucleus. Vesicles are pinched off from the outer nuclear membrane and they are united to form cistemae.
- Proteins are produced by ribosome.
- They will be transmitted to smooth E.R.
- From there they are concentrated at Golgi complex.
- From the Golgi complex the secretory vesicles are formed.
