What occurs in the absence of oxygen:
Correct answer: D. Alcoholic and lactic acid fermentation
- A. Alcoholic fermentation
- B. Respiratory electron transport chain
- C. Lactic acid fermentation
- D. Alcoholic and lactic acid fermentation
Explanation

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.
