Trace the path of a protein synthesized on a ribosome attached to the
rough endoplasmic reticulum (rough ER) as the protein travels to the
exterior of the cell. Name all the subcellular structures that the protein
passes through. In answering this question, assume that the protein is
already produced/synthesized (i.e. don't describe translation).
Describe the mRNA journey through the cell after the nucleus has given the instructions.
Describe how each organelle affects the mRNA journey as it travel through the cell and, ultimately, through the cell membrane.
Organelles you should mention include the nucleus, nuclear membrane, nucleolus, ribosomes, endoplasmic reticulum, cytoplasm, Golgi body, and plasma/cell membrane.
Imagine a protein which functions in ER but requires modification in the Golgi apparatus before it can achieve that function. Describe the protein’s path through the cell starting with protein in ER, with the help of diagram.

As the protein is made it is forced through a pore so that it ends up inside the RER. For each enzyme listed or described below state the kind of ribosome on which it's made (cytosolic, RER). If it's made on a RER ribosome, state the final destination of the protein in the endomembrane system.
