Homogenization of Rat Liver Cells Results in the Rupture of the Cell

question 26

Multiple Choice

Homogenization of rat liver cells results in the rupture of the cell membranes.Centrifugation of this homogenate compacts some of the homogenate into a pellet in 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

• A) peroxisomes.
• B) mitochondria.
• C) lysosomes.
• D) Golgi apparatus.
