Verified step by step guidance
1
Begin by understanding the definitions of anaerobic respiration and fermentation. Anaerobic respiration is a type of respiration that occurs without oxygen and involves an electron transport chain. Fermentation is a metabolic process that also occurs without oxygen but does not use an electron transport chain.
Consider the role of oxygen in both processes. Anaerobic respiration does not require oxygen, whereas fermentation also occurs in the absence of oxygen.
Examine the cellular context of each process. Anaerobic respiration can occur in various types of cells, not just yeast cells, while fermentation can occur in many different organisms, including yeast and bacteria.
Analyze the ATP yield of each process. Fermentation typically produces less ATP compared to anaerobic respiration, which can generate ATP through an electron transport chain.
Identify the key difference based on the use of the electron transport chain. Anaerobic respiration uses an electron transport chain to generate ATP, while fermentation does not involve an electron transport chain.
