Centrifugation of a cell results in the rupture of the cell membrane and the contents compacting into a 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?
Cytosol
Mitochondria
Lysosomes
Golgi bodies
Correct Answer :
B. Mitochondria
The pellet is undergoing cellular respiration, a function that occurs in the mitochondria. You can also assume that the single membrane of the cell itself is ruptured, other single membrane-bound organelles would be ruptured as well.
