Stratum Basal Which of the following does not make animals move in water? Elastic collagen stores potential energy Thyroid hormone signals when the calcium level in the blood is lower than normal. False Laboratory exercise 2 1. Which is not a symptom of parkinson’s disease? Recurrent Bleedings 2. What is the purpose of sonication? Lysing the cells to release their contents 3. Why s it important to select a good stationary phase? To retain the desired molecules and separate them from the rest of the sample. 4. Which fraction do you want to use? (700 something) 5. Which technique would you use to separate proteins by charge? Ion exchange chromatography 6. Which parameter increases the resolution in size inclusion chromatography? A moderate flow rate 7. Which part of the chromatogram represents the aSN oligomers? The one eluted at 240-280 ml 8. When would you use a vesicle model for studying cell degeneration? In experiments where the membrane needs to be tested. 9. Why do you need a negative control in your experiments? To measure how the assay works under conditions where you should not get a positive outcome 10. What is the effect of asn monomers on LUVS? None, they remain the same 11. What is the effect of asn oligomers in the vesicles? They pop them. 12. What s the effect of asn oligomerization on LUVS? Membrane permeabilization 13. How does EGCG prevent ASN toxicity? By binding to the oligomers, it blocks permeabilization Laboratory Quiz 2 1. These are aggregations of proteins in the neurons that influence the development of the disease. Alpha synuclein 2.
