Question

What role (3) does glycosylation play in the secretory pathway?

A) Signal recognition, protein stability, membrane fusion
B) Protein folding, ER exit, vesicle budding
C) Quality control, cell signaling, immune response
D) mRNA translation, ribosome binding, nuclear transport

Answer 1

Glycosylation plays important roles in protein folding, ER exit, and vesicle budding in the secretory pathway.

Step-by-step explanation:

Glycosylation plays three important roles in the secretory pathway: protein folding, ER exit, and vesicle budding.

First, glycosylation aids in protein folding by assisting in proper protein structure formation in the endoplasmic reticulum (ER).

Second, glycosylation acts as a signal for proteins to exit the ER and enter the Golgi apparatus, ensuring they are correctly targeted to their destination within the cell.

Third, glycosylation plays a role in vesicle budding, which is the process of forming vesicles that transport proteins from the Golgi apparatus to other organelles or the cell membrane.
