Question

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

Explanation:

Ribosomes are the sites of protein synthesis in cells. The cell membrane controls what enters and exits the cell. The cytoplasm is the fluid - like substance where organelles are suspended. Mitochondria are the powerhouses of the cell, generating ATP. Since the problem is about protein production, the ribosome (which is responsible for protein synthesis) is the most likely malfunctioning structure.

Answer:

C. ribosome
