Protein factory of cell is ____________?
Correct answer: C. Ribosomes
- A. Lysosome
- B. Mitochondria
- C. Ribosomes
- D. Golgi apparatus
Explanation
Ribosomes are the sites of translation, where the amino-acid sequence of a protein is assembled according to information carried by messenger RNA. Mitochondria produce much of the cell's ATP, lysosomes digest materials and the Golgi apparatus modifies and packages cell products. Students may choose mitochondria because they are called the powerhouse of the cell, but energy production is not protein synthesis.
