ENDOPLASMIC RETICULUM• Consist of membrane enclosed tubules• 2 Types of ER:
1. Rough Endoplasmic Reticulum
2. Smooth Endoplasmic Reticulum

Smooth Endoplasmic Reticulum
Ribosomes
Function: - lipid synthesis- metabolize carbohydrates- detoxification of drugs and
poisons
Structure: lack of ribosomes and made up of tubular cavities
![Page 5: Cell's Structure: ER and Golgi Bodies](https://reader035.fdocuments.us/reader035/viewer/2022062902/58ede7e91a28ab7e698b469f/html5/thumbnails/5.jpg)
Rough Endoplasmic Reticulum
Ribosomes
Structure: a system of membranous tubes and sacs covered by ribosomes
Function: concerned with the transport of proteins which are made by the ribosomes on its surface

Proteins from the RER commonly travel
to the Golgi Apparatus
![Page 7: Cell's Structure: ER and Golgi Bodies](https://reader035.fdocuments.us/reader035/viewer/2022062902/58ede7e91a28ab7e698b469f/html5/thumbnails/7.jpg)
CELL
![Page 8: Cell's Structure: ER and Golgi Bodies](https://reader035.fdocuments.us/reader035/viewer/2022062902/58ede7e91a28ab7e698b469f/html5/thumbnails/8.jpg)
Golgi Apparatus• a series of stacked
membranes (cisternae)• Have a trans and cis face• As a processing, packaging,
and transport center of carbohydrates, proteins, and glycoproteins.
![Page 9: Cell's Structure: ER and Golgi Bodies](https://reader035.fdocuments.us/reader035/viewer/2022062902/58ede7e91a28ab7e698b469f/html5/thumbnails/9.jpg)
Functions of Golgi Apparatus• It receives protein from the ER
and chemically modifies them.(e.g. carbohydrates is added to proteins to form glycoproteins)
![Page 10: Cell's Structure: ER and Golgi Bodies](https://reader035.fdocuments.us/reader035/viewer/2022062902/58ede7e91a28ab7e698b469f/html5/thumbnails/10.jpg)
Functions of Golgi Apparatus• Proteins are concentrated,
packaged, and sorted before being sent to their cellular or extracellular destinations
• Forms lysosomes

Point of ER for easy comprehension:
1. There are 2 ER in cells – rough and smooth. The Ribosomes are attached at rough ER
![Page 13: Cell's Structure: ER and Golgi Bodies](https://reader035.fdocuments.us/reader035/viewer/2022062902/58ede7e91a28ab7e698b469f/html5/thumbnails/13.jpg)
2. The function of ribosomes are to synthesize proteins.The rough ER will carry the proteins.

3. The function of smooth ER is to do both synthesize and transporting lipids.
![Page 15: Cell's Structure: ER and Golgi Bodies](https://reader035.fdocuments.us/reader035/viewer/2022062902/58ede7e91a28ab7e698b469f/html5/thumbnails/15.jpg)
4. Finally. Both proteins and lipids will be send to Golgi Apparatus to be further processed / modified and packaged and send them out of the cell.
