A) the cytosol.

Question

Quizplus · Accepted Answer

Pyruvate oxidation occurs in the mitochondrial matrix. This is where the enzymes that convert pyruvate into acetyl CoA are located. The other options are incorrect as the cytosol is where glycolysis occurs, the mitochondrial inner membrane is where the electron transport chain and ATP synthase are located, and the mitochondrial intermembrane space is the space between the inner and outer membranes of the mitochondria.
