Photo by: Lemonade. 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.
Proteins for use within the eukaryotic cell or intended for organelles such as mitochondria, chloroplasts, and peroxisomes are synthesized by mRNA molecules attached to ribosomes in the cytoplasm.
