Unit 2 - Cells and Organelles 2

Question 1

Where are proteins made?

Answer 1

Mainly at the ribosomes attached to the RER. These proteins are stored in the RER until they can be processed and packaged at the golgi apparatus. Some ribosomes are free in the cytoplasm and the proteins they produce also stay in the cytoplasm.

Question 2

Proteins are transported from the RER to the Golgi apparatus in:

Answer 2

Vesicles

Question 3

At the Golgi apparatus proteins…

Answer 3

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

Question 4

Some organelles are membrane-bound in:

Answer 4

Prokaryotic - non-membrane bound

Eukaryotic - both non-membrane bound and membrane bound

Question 5

Are ribosomes bigger in prokaryotes or eukaryotes?

Answer 5

Eukaryotes
