Proteins are synthesized at the ribosome and are often modified en route to their destination. How are these modified
proteins most likely transported within a compartmentalized eukaryotic cell?

Answer 1

B) Proteins are transported in vesicles between membrane-bound organelles.

Answer 2

Transport of modified proteins inside a compartmentalised eukaryotic cell is facilitated by golgi apparatus.

Step-by-step explanation:

Proteins are produces by the ribosomes present on the surface of rough endoplasmic reticulum. The proteins won’t be delivered to destinations as such, instead they are modified in the ER.addition of carbohydrate chain is an example of modification.

The proteins are packed into vesicles before they are released out of the ER. The transport vesicles then reach the golgi apparatus to undergo further modifications and tagging. The transport vesicles enter the golgi apparatus and undergoes modifications like addition or removal of sugar chains.

Phosphate groups will be added as tags. Then they are sorted and packaged into vesicles and they are released out of golgi. Some reach cell organelles and some fuse with cell membrane.
