question 23
the rough ers main purpose is membrane and protein production, the latter process assisted by ribosomes. these processes help maintain ______ in eukaryotic cells.

o a mrs ruhalas garden gnome collection
o b passive transport
o c homeostasis
o d vitamin synthesis

Explanation:

Homeostasis refers to the ability of an organism or cell to maintain a stable internal environment. The rough endoplasmic reticulum (ER) plays a crucial role in membrane and protein production. Proteins are essential for various cellular functions, and proper membrane composition is vital for processes like cell signaling, transport, and maintaining cell integrity. By producing membranes and proteins (with ribosome assistance), the rough ER helps the cell maintain a stable internal state, which is the essence of homeostasis. Passive transport is a mechanism of moving substances across the membrane (not related to the rough ER's main purpose here). Vitamin synthesis is not the main function of the rough ER. And "Mrs Ruhala's garden gnome collection" is clearly a distractor with no biological relevance.

Answer:

C. homeostasis
