ENDOMEMBRANE SYSTEM ORGANELLES : Endoplasmic Reticulum Nickname: Production Factory (makes proteins and lipids) Function: Internal production & delivery system of the cell. System of membranous channels and vesicles. ________ is studded with ribosomes. Site of protein synthesis and processing. ________ lacks ribosomes. Site of synthesis of phospholipids and packaging of proteins into vesicles. Images: Endomembrane system diagram, M. Ruiz, ER photomicrograph , Louisa Howard.

ENDOMEMBRANE SYSTEM ORGANELLES: _________ ___________ Nickname: Assembly Factory Functions: Takes simple molecules and puts them together into more complex macromolecules. Packages, modifies, and transports materials to different location inside/outside of the cell. Appearance: Stack of pancakes. Consists of a stack of curved saccules. Receives protein and also lipid -filled vesicles from the ER, packages, processes, and distributes them within the cell or for export out of the cell (secretion) . Also encloses digestive enzymes into membranes to form lysosomes. Images: Endomembrane system diagram, M. Ruiz, Golgi apparatus photomicrograph , Louisa Howard.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
