___________ respiration is the process by which cell utilized oxygen and produces CO2 ?
Correct answer: A. Cellular
- A. Cellular
- B. Organismic
- C. Both of these
- D. None of these
Explanation
Cellular respiration is the series of reactions in cells that uses oxygen in aerobic conditions and releases carbon dioxide while transferring energy into ATP. Students may choose organismic respiration because it describes breathing and gas exchange by the whole organism, not the intracellular energy-releasing pathway.

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.
