The endomembrane system (endo = “within”) is a group of membranes and organelles (Figure 4.4. 1) in eukaryotic cells that works together to modify, package, and transport lipids and proteins. The endomembrane system is a series of compartments that work together to package, label, and ship proteins and molecules. In your cells, the endomembrane system is made up of both the endoplasmic reticulum and the Golgi apparatus. These compartments are folds of membranes that form tubes and sacs in your cells.
