. B. Function and Evolution of Membrane-Enclosed Organelles The endomembrane system consists of the Endoplasmic Reticulum (ER), the Golgi apparatus, Lysosomes, Peroxisomes and Endosomes. The ER membrane is continuous with the nuclear envelope and the ER lumen directly communicates with the space between the outer and inner nuclear envelope membranes. . Additionally, for each of the components of the endo membrane system listed above the luminal facing lipid monolayer (See Ch 11, pages 367-368; Fig. 11-17] is different in composition from the cytosolic facing layer and the contents of the organelle (the lumen) is treated by the cell as something extracellular." a) How are these observations explained by the endomembrane origin story (the theory of how endomembrane compartments evolved through cl toplasmic membrane invaginations) depicted in Figure 15-3, page 491, b) The theory specifically refers to the formation of the nuclear envelope but it is thought that the Golgi complex arose in a similar fashion What might that have looked like? Draw a sketch (or series of sketches) depicting a possible scenario.
