Which organelle houses the citric acid cycle?

Explanation:
The citric acid cycle happens in the mitochondrial matrix, the space inside the inner mitochondrial membrane. This location houses the enzymes that drive the cycle, starting from acetyl-CoA and regenerating oxaloacetate while releasing CO2 and producing NADH and FADH2. Those reduced carriers then feed the electron transport chain on the inner membrane, linking the two stages of cellular respiration. The cytoplasm carries glycolysis, the nucleus houses genetic material, and the Golgi apparatus is involved in protein processing, so they aren’t the sites for the citric acid cycle.
