The endoplasmic reticulum (ER) is a series of interconnected membranes or flattened sacs adjacent and connected to the nuclear membrane. The ER comes in two different morphological forms: smooth endoplasmic reticulum (sER) and rough endoplasmic reticulum (rER). The primary function of the sER is to serve as a platform for the synthesis of lipids (fats), carbohydrate (sugars) metabolism , and the detoxification of drugs and other toxins.
rough ER, it has ribosomes on it. RER makes/modifies/processes proteins that will be used outside the cell or in a distant place in the cell. What is SER? smooth ER, has no ribosomes. its where membranes are made and where other lipids are made/modifies/processed.
