AThe vacuoles
BThe ribosomes
CThe peroxisomes
DThe centrioles
Answer & Solution
Correct answer: B. The ribosomes
1. Proteins are built from amino acids, and the job of assembling them belongs to one structure.
2. Ribosomes are the cellular structures responsible for protein synthesis.
3. Vacuoles store and transport materials, and peroxisomes run oxidation reactions, so neither builds proteins.
4. Because the job is essential, ribosomes turn up in practically every cell.
