I gave my students this multiple choice question: All living things are made up of prokaryotic or eukaryotic cells. Which function is found in both prokaryotic and eukaryotic cells?

Only one answer is correct among these 4 choices:
- aerobic respiration
- sexual reproduction
- protein production
- nitrogen fixation

Could you tell me which one is correct?

protein production
