Congenital disorders of glycosylation are a growing class of rare diseases. Which organelle would be most commonly involved in the glycoprotein disorder portion of the group?

RER

ribosomes

endosomes

Golgi apparatus

The correct answer will be option-Golgi apparatus.

Explanation:

Golgi apparatus is a part of the endomembrane system which is responsible for the modification and transport of the protein through vesicles.

The modification like glycosylation adds glycosyl donor-long sugar chains to another functional group of proteins. The congenital disorders of glycosylation affect the glycosylation process as the individuals lack an enzyme required for the glycosylation.

Since glycosylation of proteins takes place in the Golgi apparatus, the option-Golgi apparatus is the correct answer.
