Question

a diseased cell is no longer able to produce proteins. which cell structure is most likely malfunctioning?
○ cell membrane
○ cytoplasm
○ ribosome
○ mitochondrion

Explanation:

• Cell membrane: Controls substance entry/exit, not protein production.
• Cytoplasm: Holds organelles, not direct protein synthesis.
• Ribosome: Site of protein synthesis (translation), so malfunction here stops protein production.
• Mitochondrion: Produces energy (ATP), not proteins.

Answer:

C. ribosome
