Question

Which of the following best describes the role of the Golgi apparatus in a cell?

• A. It synthesizes proteins.
• B. It stores water and waste products.
• C. It modifies, sorts, and packages proteins for secretion.
• D. It is responsible for cellular respiration.

Hint:

The Golgi apparatus is essential for the processing and packaging of proteins and lipids, ensuring that they reach their correct destinations in the cell or are secreted.

Answer 1

The Correct Option is C

The Golgi apparatus, often referred to as the "post office" of the cell, plays a crucial role in modifying, sorting, and packaging proteins and lipids that have been synthesized in the endoplasmic reticulum (ER). After proteins are synthesized in the rough ER, they are transported to the Golgi apparatus, where they undergo further modifications such as the addition of carbohydrate groups (glycosylation). The Golgi apparatus then sorts these proteins and lipids and packages them into vesicles, which can be transported to their final destinations, including secretion outside the cell. Thus, the primary function of the Golgi apparatus is to modify, sort, and package proteins for secretion.
