TESTE DEIN WISSEN

How can differences in bacterial and mammalian structure and function be exploited by medicine?

Lösung anzeigen
TESTE DEIN WISSEN

Genetic engineering for insulin production:

  • Insulin gene inserted into gap of plasmid and reinserted into bacteria to allow for reproduction
  • Mass production

Antibiotics:

  • Allows antibiotics to enter cell through a bacterium

TESTE DEIN WISSEN

What are the differences in heterochromatin and euchromatin when viewing cell in microscope?

Lösung anzeigen
TESTE DEIN WISSEN

Heterochromatin appears darker when stained - DNA molecules are more dense as they are packed in nucleosome form and are transcriptionally inactive.

Euchromatin appears lighter when stained - DNA molecules are loosely packaged where DNA is able to be transcribed.

TESTE DEIN WISSEN

Name 4 enzymes secreted by pancreatic exocrine cells.

Lösung anzeigen
TESTE DEIN WISSEN
  • Trypsin & Chromotrypsin - digests proteins
  • Lipase - digests lipids
  • Amylase - digests carbohydrates
Lösung ausblenden
TESTE DEIN WISSEN

What are zymogen granules?

Lösung anzeigen
TESTE DEIN WISSEN

Zymogens are inactive precursors of enzymes.

They are only activated via a reaction e.g. hydrolysis that may cause a conformational change to allow their active site to be exposed - thus activating the enzyme for its function. A granule would contain a lot of the specific zymogens.

TESTE DEIN WISSEN

Which vesicles arrive and emerge from the golgi body?

Lösung anzeigen
TESTE DEIN WISSEN

Vesicles arrive at the cis face

  • These contain proteins from the ER

Vesicles emerge from the trans face (vesicles are seen forming)

  • These contain modified proteins
