Mitochondria is the place where eukaryotes undergo oxidative metabolism, and it is also the place where sugar, fat and amino acids are finally oxidized to release energy. Mitochondria are responsible for final oxidation through tricarboxylic acid cycle and oxidative phosphorylation, which correspond to the second and third stages of aerobic respiration respectively. The glycolysis completed in the cytoplasm matrix and the tricarboxylic acid cycle completed in the mitochondria matrix will produce high-energy molecules such as reduced nicotinamide adenine dinucleotide and reduced flavin adenine dinucleotide, and the role of oxidative phosphorylation is to use these substances to reduce oxygen and release energy to synthesize ATP.

During aerobic respiration, 1 molecule glucose releases energy through glycolysis, tricarboxylic acid cycle and oxidative phosphorylation, which can produce 30 ~ 32 molecules of ATP.
