A diseased cell is no longer able to produce proteins. Which cell structure is most likely malfunctioning?

cell membrane
cytoplasm
ribosome
mitochondrion

The ribosome is the cell structure most likely malfunctioning in this case. Ribosomes are responsible for protein synthesis within the cell. If a diseased cell is unable to produce proteins, it suggests that the ribosome is not functioning correctly.

The most likely malfunctioning cell structure in this scenario is the ribosome. Ribosomes are responsible for protein synthesis within the cell. If a diseased cell is unable to produce proteins, it suggests that the ribosomes within the cell are malfunctioning.
