Endomembrane System Left-side Interactive NoteBook Drawing

For this assignment, you will be asked to create a poster that shows the relationship between different parts of the endomembrane system.

In your IntNB, you will need to show the following:

– Nucleolus making ribosomes– Ribosomes being shipped out of nucleus to become either free or attached– Proteins being made by free ribosomes in the cytoplasm– Protein being made by attached ribosomes of RER– Protein folding inside the RER– Protein being modified by the Golgi– Vesicles moving from RER to Golgi – Vesicles leaving the Golgi and fusing to the cell membrane, releasing its protein

contents– Vesicles leaving the Golgi and becoming a lysosome

Blown-up view of the cell membrane (with phospholipid and proteins)

Be sure to label in your drawing: Nucleus, Nuclear Pore, Nucleolus, Free Ribosome, Attached Ribosome, Rough ER, Vesicles, Protein, Lysosome, Cell Membrane, Phospholipid

Your drawing should be neat, colored, and in final draft form.
