Question

question: 10
which statement best describes how cell organelles interact to maintain homeostasis?

a. ribosomes contain enzymes, which are used to break down and recycle cell wastes.

b. the golgi apparatus packages proteins into vesicles, which are released by the cell membrane.

c. the nucleus modifies and sorts proteins, which are released from the rough endoplasmic reticulum.

d. mitochondria create and store lipids, which are used to make the phospholipid bilayer of the cell membrane.

Explanation:

• Option A: Ribosomes are for protein synthesis, not breaking down wastes (lysosomes do that), so A is wrong.
• Option B: The Golgi apparatus modifies and packages proteins into vesicles, which can then fuse with the cell membrane to release the proteins, helping maintain homeostasis (e.g., secreting enzymes or signaling molecules). This is correct.
• Option C: The nucleus contains DNA and controls the cell; the Golgi apparatus modifies/sorts proteins, not the nucleus, so C is wrong.
• Option D: Mitochondria produce ATP (energy), not create/store lipids (smooth ER is involved in lipid synthesis), so D is wrong.

Answer:

B. The Golgi apparatus packages proteins into vesicles, which are released by the cell membrane.
