Aerobic respiration is a pathway involving a series of reactions. What is the final reaction in the pathway?
Correct answer: C. The reduction of oxygen to water
- A. The formation of carbon dioxide
- B. The oxidation of cytochrome
- C. The reduction of oxygen to water
- D. The synthesis of ATP
Explanation
c) The reduction of oxygen to water:The reduction of oxygen to water is the final reaction in aerobic respiration. It occurs in the last step of the electron transport chain, where oxygen serves as the final electron acceptor. This reaction combines electrons, protons, and oxygen to produce water.

About Cellular Respiration
Cellular respiration releases energy from glucose through glycolysis, the link reaction, the Krebs cycle and the electron transport chain, producing ATP. The pathway differs in oxygen availability: aerobic respiration uses oxygen and yields more ATP, while anaerobic respiration produces much less ATP and forms lactic acid in muscles or ethanol and carbon dioxide in yeast.
