Question

Respiratory enzymes are localized in the

• A. Ribosomes.
• B. Chloroplast.
• C. Mitochondria.
• D. None of the above.

Answer 1

The correct option is C Mitochondria.

The process of glycolysis is the common process between aerobic and anaerobic respiration. The glycolysis occurs in cytoplasm and results in production of two molecules of pyruvic acid from one molecule of glucose. No oxygen is consumed nor any carbon dioxide is evolved during glycolysis. The pyruvic acid is further metabolised in mitochondria. Respiratory enzymes for metabolism of pyruvate are located in the mitochondrial matrix and inner mitochondrial membrane.
