Florida Biology EOC Practice Test

Ribosomes are specialized structures found in cells that are responsible for protein synthesis. They are composed of RNA and protein and are the site of translation, the process by which genetic information in ribonucleic acid (RNA) is used to create proteins. This process is essential for the growth, development, and maintenance of all living organisms. Option B, detoxifying harmful substances, is incorrect because ribosomes do not have the ability to detoxify substances. Option C, modifying and storing proteins, is incorrect because while ribosomes play a role in protein modification, that is not their primary function. Option D, breaking down large molecules, is incorrect because ribosomes do not have the ability to break down substances.
