Which one of the following does not take place in the mitochondrial matrix?

Question

BlackTom AI · Accepted Answer

To evaluate where each process occurs, consider the cellular compartments involved.
Option 1: glycolysis. This pathway breaks glucose into pyruvate and takes place in the cytosol of the cell, not inside mitochondria, so it does not occur in the mitochondrial matrix.
Option 2: citric acid cycle (Krebs cycle). This cycle runs within the mitochondrial matrix, where acetyl-CoA is oxidized to CO2 with the production of NADH and FADH2, so it clearly takes place in the matrix.
Option 3: pyruvate processing (pyruvate dehydrogenase complex). Before entering the citric acid cycle, pyruvate is decarboxylated and converted to acetyl-CoA by the pyruvate dehydrogenase complex, a reaction that occurs in the mitochondrial matrix, not elsewhere.
In summary, glycolysis is the pathway that does not take place in the mitochondrial matrix, whereas the citric acid cycle and pyruvate processing both occur inside the matrix.
