Complete question:

Homogenization of rat liver cells results in the rupture of the cell membranes. Centrifugation of this homogenate compacts some of the homogenates into a pellet at the bottom of the centrifuge tube. Bathing this pellet with a solution containing succinate (a four-carbon organic compound), phosphate ions, oxygen, and ADP yields metabolic activity, including the production of ATP and the uptake of oxygen. This pellet most likely contains

1.peroxisomes

2.mitochondria

3.lysosome

4.Golgi complex

5.endoplasmic reticulum

2. Mitochondria

Explanation:

Mitochondria are one of the biggest organelles in the cell. They degrade organic molecules, releasing chemical energy from their bindings through a process that consumes oxygen: cellular respiration.

The released energy is stored as ATP through the cellular respiration process and then is used in other cellular activities.

Mitochondria are more grouped in areas or tissues with higher energetical requirements.

As cellular respiration characterizes by consuming oxygen and producing ATP, we can assume that the pellet mostly contains mitochondria.
