A scientist performed an experiment to separate the organelles in an animal cell according to mass. The scientist combined the cells with a buffer solution that had the same water potential as the cells and then broke open the cells. The mixture was centrifuged several times to produce pellet 1, pellet 2, pellet 3 and pellet 4, with each pellet containing one organelle. What is the function of the organelle obtained in pellet 3?
- Adigestion of old organelles
- Bproduction of ATP
- Csynthesis of mRNA
- Dsynthesis of protein
