Question

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. (1 point) ○ protein making and protein packaging ○ dna making and dna packaging ○ dna packaging and dna storing ○ protein packaging and lipid production

Explanation:

To solve this, we recall the functions of the rough endoplasmic reticulum (RER) and Golgi apparatus. The RER has ribosomes and is involved in protein synthesis (making proteins). The Golgi apparatus modifies, sorts, and packages proteins (packaging proteins). Now we analyze the options:

• Option 1: "protein making and protein packaging" matches RER (protein making) and Golgi (protein packaging) functions.
• Option 2: RER and Golgi are not involved in DNA making/packaging, so this is incorrect.
• Option 3: RER and Golgi don't handle DNA packaging/storing, incorrect.
• Option 4: Golgi is for protein packaging, not lipid production (smooth ER does lipid production), and RER isn't for protein packaging (Golgi is), so incorrect.

Answer:

A. protein making and protein packaging
