U8 Intro to Protein Sorting

Question 1

Is Mitochondria considered to be part of the endomembrane system?

Answer 1

No! Derived from external organisms

Question 2

What is the endosymbiont hypothesis?

Answer 2

Mitochondria&Chloroplasts evolved from a prokaryotic cell being engulfed by pre-eukaryotic cell
–> transcription&translation happen within the cytoplasm, NOT the nucleus
–> circular genome w/ operons
–> replicate via binary fission

Question 3

Where do transported proteins arrive after going through nuclear pores?

Answer 3

the brain/head of the cell
-The Nucleus

Question 4

Where do proteins being transported across membranes end up?

Answer 4

the organelles in the middle
-Chloroplast
-Mitochondria
-ER

Question 5

ANIMAL CELLS HAVE DIRECTIONALITY

Answer 5

Remember this :3

Question 6

Where do proteins being transported by vesicles arrive?

Answer 6

the organelles at the base of the cell
-Golgi Apparatus
-Endosomes
-Lysosomes
-Plasma Membrane
-Extracellular space
