Question

question 7 (10 points) listen proteins are processed and modified in the interior of the rer. ribosomes. nucleus. chloroplasts.

Explanation:

• RER (Rough Endoplasmic Reticulum) has ribosomes on its surface; after ribosomes synthesize proteins, the interior (lumen) of RER is where proteins undergo processing and modification (like folding, adding sugar groups).
• Ribosomes only synthesize proteins, not modify them.
• The nucleus stores genetic material, not processes proteins.
• Chloroplasts are for photosynthesis, not protein modification.

Answer:

A. RER.
