Centrifugation of a cell results in the rupture of the cell membrane and the contents compacting into pellets in the bottom of the centrifuge tube. Bathing this pellet with a glucose solution yields metabolic activity including the production of ATP. One of the contents of this pellet is most likely which of the following?

A. Centrifugation of a cell results in the rupture of the cell membrane and the contents compacting into pellets in the bottom of the centrifuge tube.
B. Bathing this pellet with a glucose solution yields metabolic activity including the production of ATP.

Most likely it should be Mitochondria.  

Explanation:

Centrifugation of cells :

At first, large components undergo precipitation such as whole-cell nuclei, cytoskeleton. They form a pellet at the bottom of the centrifuge tube at a low speed. Then at medium speed mitochondria, lysosome, peroxisomes form the pellet and after that at higher speed microsomes, small vesicles form a pellet. At last at very high speed, ribosomes, viruses, and macromolecules form their pellet.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
