A protein enters the endomembrane system by being synthesized on ribosomes attached to the rough endoplasmic reticulum (ER). It then undergoes modifications and folding within the ER before being transported in vesicles to the Golgi apparatus. In the Golgi apparatus, further processing occurs before the protein is sorted and directed to its final destination within the cell.
The organelles that are a part of the endomembrane system include the endoplasmic reticulum, Golgi apparatus, lysosomes, vesicles, and the nuclear envelope. The endomembrane system is a network of membranous organelles within a eukaryotic cell that work together to transport proteins, lipids, and other molecules throughout the cell and to the cell membrane. It plays a key role in protein synthesis, processing, and trafficking within the cell.
The endomembrane system includes various organelles such as the endoplasmic reticulum, Golgi apparatus, lysosomes, vesicles, and the plasma membrane. However, it does not include mitochondria and chloroplasts, as these organelles are not part of the endomembrane system and have their own distinct membranes and functions. Additionally, the nucleus is often considered separate from the endomembrane system despite its membrane structure.
The Golgi apparatus is part of the endomembrane system
The endomembrane system consists of organelles such as the endoplasmic reticulum, Golgi apparatus, vesicles, and lysosomes. The process begins with protein synthesis in the rough ER, followed by modification and packaging in the Golgi apparatus. Vesicles transport molecules between organelles, while lysosomes break down waste materials.
In your cell, this is where the endomembrane system comes in a cell image because one is studded with small ribosomes and one is not.

No, the endomembrane system lies between the nuclear envelope and the cell membrane; dis-including both. The Endoplasmic reticulum and the Golgi apparatus are two members of the endomembrane system. Google endomembrane system to get the complete picture.
No. The endomembrane system consists of the endoplasmic reticulum and the Golgi apparatus - i.e things that are formed within the cell. The mitochondria was originally formed from a captured bacterial cell - as it has it's own DNA and its own ribosomes (as well as very bacterial like proteins). It is a separate organelle on its own, although it will have connections with the endomembrane system it is not considered part of it.

The lipid and protein composition of membranes in the endomembrane system is largely determined by the specific functions of each organelle. For example, the Golgi apparatus has a different lipid and protein composition compared to the endoplasmic reticulum to support its role in protein modification and sorting. Additionally, enzymes and transport proteins present in each organelle contribute to the unique composition of their membranes.

producing, sorting and packaging material
Proteins are moved from the rough endoplasmic reticulum (ER) to the Golgi apparatus, where they are modified and sorted for transport to different destinations. From the Golgi, proteins can be sent to various organelles such as lysosomes or secretory vesicles for secretion outside the cell. The endomembrane system helps regulate protein trafficking and ensures proper targeting of proteins to their final cellular locations.
