What type of respiration requires oxygen to proceed?

• A. Aerobic Respiration
• B. Anaerobic Respiration
• C. Fermentation
• D. Glycolysis

Answer: (A)

The type of respiration that requires oxygen is aerobic respiration. This process occurs in the mitochondria of cells and is essential for the efficient production of ATP, the energy currency of the cell. During aerobic respiration, glucose is completely oxidized, resulting in a significant yield of ATP, carbon dioxide, and water. The presence of oxygen allows for the complete breakdown of glucose through a series of reactions including glycolysis, the citric acid cycle, and oxidative phosphorylation, which together maximize energy extraction from substrates. On the other hand, anaerobic respiration and fermentation occur in the absence of oxygen and yield much less ATP compared to aerobic respiration. Glycolysis, while it can occur in both aerobic and anaerobic conditions, does not itself require oxygen; it is the first step in both pathways. Therefore, the distinction that aerobic respiration requires oxygen is crucial for understanding cellular energy production.
