What we expect you to know
Terminology
You should know, what these terms mean and you should be able to explain them in your own words.
Compartments . ER . Golgi . Exocytosis . Endocytosis . Trans Golgi Network . Multivesicular Body . Exosomes . Clathrin . Cotranslational and posttranslational transport . vSNARES . tSNARES . Cellulose synthase . Microfibril
Content
-
You can explain, what compartments are, and what they are good for
-
You can sketch down the path of an organelle and of a secreted protein
-
You can name one animal and one plant example for signalling through vesicle transport
-
You can explain, how the cell wall is synthetised and what are old and young layers
-
You can explain, how polar auxin transport is generated
Vertiefung (for Bachelor students)
- 1. Is a nucleus a compartment? Justify your answer
- 2. A small ribosomal subunit from spinach needs 10 hours in your centrifugation set-up to reach its final destination. How long does the large ribosomal subunit need?
- 3. In a study on a novel peptoid targeting mitochondria, we observed that Wortmannin blocked the uptake completely, while Ikarugamycin did not block uptake. What is your explanation?
- 4. The fungus Botrytis cinerea secretes exosomes with miRNA to block plant defence. As charged molecule, miRNA cannot pass the plant membrane. How does this work then?
- 5. How would the shape of a root hair change, when you destroy actin filaments with the inhibitor Latrunculin B?
- 6. Plasmolysis is often used as test to find out, whether a plant cell is alive? Why does this work?
