Question

imagine you are investigating cells that are not processing proteins correctly. upon closer examination, you find that the proteins are missing specific sugar groups. based on this information, what part of the endomembrane system is defective in these cells?

motor proteins

ribosomes

transport vesicles

golgi

Explanation:

The Golgi apparatus is responsible for modifying proteins by adding sugar groups (glycosylation) as part of protein - processing in the endomembrane system. Motor proteins are for movement, ribosomes are for protein synthesis, and transport vesicles are for moving materials between organelles.

Answer:

Golgi
