Question

which stage of aerobic respiration also occurs during fermentation?
a glycolysis
b electron transport
c krebs cycle

Explanation:

Aerobic respiration has three stages: glycolysis, Krebs cycle, and electron transport chain. Fermentation is an anaerobic process. Glycolysis occurs in both aerobic respiration (when oxygen is available, and the process continues to Krebs cycle and electron transport chain) and fermentation (when oxygen is not available, and after glycolysis, the pyruvate is converted into other products like ethanol or lactic acid instead of entering the Krebs cycle). The Krebs cycle and electron transport chain require oxygen and do not occur in fermentation.

Answer:

A. glycolysis
