Mitochondria is called as the power house of cell because energy production through aerobic respiration occurs in mitochondria. The process of energy production in mitochondria can be divided into parts - Krebs cycle and oxidative phosphorylation. Fumaric acid hydration is catalyzed by an enzyme fumarase during Krebs cycle and cytochrome oxidation is catalyzed by cytochrome oxidase during oxidative phosphorylation. Glycine decarboxylation is also carried out by mitochondria. Glyceraldehyde - 3 - phosphate dehydrogenation is carried out by the enzyme glyceraldehyde - 3 - phosphate dehydrogenase. This reaction is catalyzed during glycolysis in the cytoplasm of a cell. Thus, the correct answer is option B.
