Unit 1 Section 1: Organelles Working together

Question 1

Proteins are made…(where?)

Answer 1

at the ribosomes on the RER. some ribosomes are free In the cytoplasm and the proteins they produce also stay in the cytoplasm.

Question 2

in the RER proteins are…

Answer 2

folded and processed, being modified in ways such as having sugar chains added.

Question 3

<p>

| proteins are transported from the RER to the...</p>

Answer 3

<p>
	Golgi apparatus(body) in vesicles.</p>

Question 4

at the Golgi apparatus the proteins…

Answer 4

undergo further processing where sugar chains are trimmed or more are added

Question 5

proteins are transported in/out/around cells in…

Answer 5

vesicles

Question 6

proteins may be stored…(where?)

Answer 6

in the rough endoplasmic reticulum until they are needed by the Golgi apparatus

Question 7

the cytoskeleton is made of

Answer 7

protein threads

Question 8

cytoskeleton protein threads are arranged as

Answer 8

microfilaments- small solid strands
and
microtubules - tiny protein cylinders

Question 9

microtubules and microfilaments

Answer 9

support the cell’s organelles keeping them in position,
strenghthen the cell and help maintain it’s shape,
they’re responsible for the transport of organelles and materials within the cell.
