Document Summary

Last class we began our discussion of eukaryotic cell structure. We talked about the double membrane organelles- the nucleus the mitochondria and the plastids. What is the minimum number of times that a ribosomal protein passes through a nuclear pore, before it can participate in translation: 0, 1, 2 **, 3. We began to see how extensively eukaryotes use membranes to make internal compartments. Now we will talk about the endomembrane system, and we will see yet again how extensively eukaryotic cells use membranes: the endomembrane system. Now let"s talk about the major organelle-system of the cytoplasm - the endomembrane system. The endomembrane system is shown on page 76 as the brown sac system plus the blue sac system. It is also shown on page 77 brown sacs and blue sacs. It is also shown on page 101, figure 5. 5- without the other cellular components. It is a collection of interconnected organelles that collectively are called the endomembrane system.
