- A) fermentation
- B) glycolysis
- C) photorespiration
- D) aerobic respiration
Answer: A) fermentation
Explanation: During fermentation, the respiratory substrate is partially oxidised without an external electron acceptor. During aerobic respiration, oxygen acts as an external electron acceptor. Glycolysis is the common step in both aerobic and anaerobic respiration (fermentation).
