Which of the following metabolic processes occurs exclusively in the mitochondria?
Correct Answer: Ketone body synthesis
Description: Of the processes listed, only ketone body synthesis occurs exclusively in the mitochondria. Other mitochondrial processes include the production of acetyl-CoA, the TCA cycle, the electron transpo chain, and fatty acid oxidation. Processes that occur exclusively in the cytoplasm include cholesterol synthesis (in cytosol or in ER), fatty acid synthesis, glycolysis, and the hexose monophosphate shunt. Note that gluconeogenesis and the urea cycle occur in both the mitochondria and the cytoplasm. Ref: Botham K.M., Mayes P.A. (2011). Chapter 22. Oxidation of Fatty Acids: Ketogenesis. In D.A.
