Kind of cellular respiration which occurs in presence of oxygen is _________ ?
Correct answer: B. Aerobic respiration
- A. Anaerobic respiration
- B. Aerobic respiration
- C. Nitrogenous respiration
- D. Acidic respiration
Explanation
Aerobic respiration uses oxygen as the final electron acceptor and generally releases much more ATP than anaerobic respiration. Students may choose anaerobic respiration because both processes release energy from food, but anaerobic respiration occurs without oxygen.

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.
