What is the primary difference between fermentation and anaerobic respiration?
A
Fermentation requires mitochondria, while anaerobic respiration occurs in the cytoplasm.
B
Fermentation occurs in the presence of oxygen, while anaerobic respiration does not.
C
Fermentation generates more ATP than anaerobic respiration.
D
Fermentation produces alcohol or lactic acid, while anaerobic respiration uses an electron transport chain.
Verified step by step guidance1
Understand that both fermentation and anaerobic respiration are processes that cells use to generate energy in the absence of oxygen.
Recognize that fermentation occurs in the cytoplasm and does not involve an electron transport chain, resulting in the production of alcohol (in yeast) or lactic acid (in muscle cells).
Identify that anaerobic respiration, unlike fermentation, involves an electron transport chain, which is typically located in the cell membrane of prokaryotes or the mitochondria of eukaryotes.
Note that fermentation does not require mitochondria and is a simpler process compared to anaerobic respiration, which is more complex due to the involvement of an electron transport chain.
Conclude that the primary difference is that fermentation results in the production of alcohol or lactic acid, while anaerobic respiration involves an electron transport chain to generate energy.
