The common phase between aerobic and anaerobic respiration is called:
Correct answer: A. Glycolysis
- A. Glycolysis
- B. Tricarboxylic acid cycle
- C. Oxidative phosphorylation
- D. Krebs cycle
Explanation
Glycolysis occurs in the cytoplasm and breaks down one glucose molecule into two molecules of pyruvate, releasing a small amount of ATP and NADH. This process does not require oxygen, so it takes place in both aerobic and anaerobic respiration.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
