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.
Ribosomes. Ribosomes are found in both plant and animal cells and are made in the nucleolus and transported out of the nucleus through endoplasmic reticulum. Ribosomes are important for the process of synthesis, specifically of proteins.ough Endoplasmic Reticulum: The RER is called rough because of the ribosomes attached to it. The Rough ER is necessary to create and transport proteins throughout the cell. When the ribosomes attached to the Rough ER create proteins, the proteins are sent to the Rough ER to be chemically modified for specific uses.
