Centrifugation of a cell results in the rupture of the cell membrane and the compacting of the contents into a pellet 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) Cytosol
B) Mitochondria
C) Lysosomes
D) Golgi bodies
E) Thylakoids

Question

Quizplus · Accepted Answer

Mitochondria are organelles responsible for cellular respiration and the production of ATP. Bathing the pellet with glucose solution would provide the necessary substrate for mitochondrial ATP production. Cytosol, lysosomes, Golgi bodies, and thylakoids are unlikely to produce ATP on their own, and therefore less likely to be present in the pellet.
