Correct answer: Both begin with glycolysis.
Explanation:
- Glycolysis (in the cytosol) is the first pathway for breaking down glucose in both aerobic and anaerobic processes.
- Aerobic respiration proceeds into the mitochondria and uses oxygen and an electron transport chain; anaerobic fermentation does not require oxygen, does not use mitochondria, and ends with fermentation products (e.g., lactate or ethanol), not the mitochondrial ETC.
- (Note: some prokaryotes perform anaerobic respiration using an electron transport chain with non‑oxygen terminal acceptors — but in typical biology contexts “anaerobic respiration”/fermentation lacks the mitochondrial ETC.)
