Proteins are important molecules that are synthesized, transported, and used in cells in a multitude of ways. The rough endoplasmic reticulum and Golgi apparatus have parts to play in this system. These functions are __________, respectively. Identify the answer choice that correctly fills in the blank in the above passage.

protein making and protein packaging

The correct answer choice that fills in the blank in the above passage is "protein making and protein packaging."

The correct answer choice that fills in the blank in the above passage is "protein making and protein packaging."

To arrive at this answer, let's understand the functions of the rough endoplasmic reticulum (ER) and the Golgi apparatus:

1. Rough Endoplasmic Reticulum (ER): The rough ER is involved in protein synthesis, specifically the production of proteins. It has ribosomes attached to its surface, which are responsible for protein synthesis. These ribosomes produce proteins that will either stay within the ER or be transported to other cellular locations.

2. Golgi Apparatus: The Golgi apparatus is responsible for modifying, processing, and sorting proteins and lipids. It receives proteins from the ER and modifies them by adding sugars or other molecules to them. It then sorts and packages these modified proteins into vesicles, which can be transported to their final destinations inside or outside of the cell.

In the context of the passage, the rough ER is involved in "protein making," referring to the synthesis of proteins, while the Golgi apparatus is involved in "protein packaging," referring to the modification, sorting, and packaging of proteins into vesicles. Thus, the correct answer choice is "protein making and protein packaging."
