Which organelle is the site of glucose oxidation to produce ATP in energy production?

Explanation:
Glucose oxidation to produce ATP is carried out mainly by cellular respiration inside mitochondria. After glycolysis in the cytosol, pyruvate enters the mitochondrion and is converted to acetyl-CoA, which feeds the citric acid cycle. This cycle generates NADH and FADH2 that feed the electron transport chain on the inner mitochondrial membrane. The electron flow creates a proton gradient used by ATP synthase to make ATP, so most of the cell’s ATP comes from this oxidative phosphorylation process in the mitochondria. Chloroplasts handle photosynthesis, not glucose oxidation; ribosomes build proteins, and the Golgi apparatus processes and ships molecules.
