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.
nucleolus is inside the nucleus and it makes ribosomes. Ribosomes are made up of mRNAs and proteins and it is the site for making proteins. There are ribosomes on some of the â¦ ER (endoplasmic reticulum) and so the ER is known as rough ER. As more proteins are made, they leave the rough ER via vesicles that bud off from the ER.
