If a toxic chemical destroys the ribosomes, which cellular activity would be affected
first?

Protein production will be affected if a toxic chemical destroys the ribosomes.

Explanation:

Ribosomes are a cell structure that makes protein. Protein is one of the most important Biomolecules which is required by the cell to carry out cellular process.

Ribosomes can be discovered gliding inside the cytoplasm or embedded to the endoplasmic reticulum.  The area of the ribosomes in cell figures out what sort of protein it makes.

The protein synthesized by the free floating ribosomes are used by the cell for inter cellular functions, whereas the protein synthesized by the ribosomes embedded on endoplasmic reticulum is used for both inner as well as outer functioning of the cells.  

structure is maintained and sustained by:

-cytoskeleton: gives cells coherence

-cell wall: support

-cytoplasm: shape

hope this .

true is the final answer!
