You were working with mouse mitochondrial proteins, and as a routine, you have isolated muscle tissues and homogenized it in ice-cold conditions. Following homogenization, purification was carried out by differential velocity centrifugation, equilibrium density gradient centrifugation, and finally, you have collected the fractions. But you have failed to detect any mitochondrial marker enzyme citrate synthase activity in the fractions. When you visualized the samples under the microscopes, you observed broken organelle debris due to severe proteolytic degradation. Which of the following statement may justify the cause of this result?
