Homework Answers
ANSWER :
In biochemistry, the differential centrifugation is a method to separate cellular organelles and other sub-cellular particles on the basis of their sedimentation rate. The correct order for fraction separation is as follows ;-
Nuclear > Mitochondrial > Membrane > Cytosol.
Hence option (B) is the correct answer.

What happens to the O2 produced by photosynthesis in chloroplasts? Choose one: O It is oxidized by the citric acid cycle in the mitochondrial matrix. o It donates electrons to the mitochondrial electron-transport chain. O It is converted to the CO2 used in carbon fixation in the chloroplast stroma. o It serves as the final electron acceptor in the photosynthetic electron-transport chain. O It is consumed by oxidative phosphorylation in mitochondria. In eukaryotic cells, where does the conversion of CO2...
