Question

The organelles and biomolecules present in homogenized cells can be separated by centrifugation. Which of the following would be found at the top of a centrifugation gradient?

Answer 1

Answer:

ATP molecules

Explanation:

Density centrifugation is a method that separates components of a sample on the basis of their density or density gradient.

During centrifugation the sample will be layered according to their density and that is the principle of density centrifugation.

When centrifuging a sample containing homogenized cells. ATP molecules will be found at the top of the centrifugation  gradient due to having a lighter density compared to the rest of the molecules.
