Question 1

Components of the Endomembrane System

Answer 1

• plasma mem
• lysosome
• nuclear envelope
• Golgi Complex
• Rough ER
• Smooth ER
• Peroxisomes

Question 2

What classifies to be in the Endomembrane Sys

Answer 2

-Vesicles fuse and off of

Question 3

What are the roles of the Endomembrane sys.

Answer 3

• move mem around

- produce and move proteins

Question 4

What are NOT component of the ED and why

Answer 4

• Mitochondria and Chloroplast :
• > no moving mem or fusion vesicles
• > uses binary fission to grow and multiply
• > phospholipids exchange proteins

Question 5

Endoplasmic Reticulum
-structure
*Rough
~Smooth

Answer 5

• flippase synthesis mem
• made up of cisternae +lumen
• binds proteins for secretion
  *initial folding+assembly of subunits
  *intial glycosyation @lumin
  ~ hydroxylation(detoxifi)
  ~Ca storage @muscles
  ~Steroid synth
  ~Carbo metabolism

Question 6

Golgi Complex

Answer 6

• cisternae and lumen
• Cis-GN(same side) VS Trans-GN (away from nucleus)
• Anterograde(nucleus to mem) VS Retrograde (TGN to CGN)
• –> uses cytoskeleton as tracks along with motor molecules to move vesicles around
• Glycosylation/procession (cleaving)
• Signal Sequence (Protein Sorting)
