What is the primary purpose of fermentation in organic chemistry?
A
To produce ATP through oxidative phosphorylation
B
To convert glucose into ethanol and carbon dioxide

Verified step by step guidance1
Understand that fermentation is a metabolic process that converts sugar to acids, gases, or alcohol. In the context of organic chemistry, it often refers to the conversion of glucose to ethanol and carbon dioxide.
Recognize that fermentation is an anaerobic process, meaning it does not require oxygen. This is crucial in environments where oxygen is scarce.
Identify the main chemical reaction involved in fermentation: C₆H₁₂O₆ (glucose) → 2 C₂H₅OH (ethanol) + 2 CO₂ (carbon dioxide). This reaction highlights the conversion of glucose into ethanol and carbon dioxide.
Note that fermentation is not primarily for ATP production through oxidative phosphorylation, which is an aerobic process. Instead, it allows cells to regenerate NAD⁺ from NADH, enabling glycolysis to continue producing ATP anaerobically.
Clarify that fermentation is not involved in synthesizing proteins from amino acids or breaking down lipids into fatty acids and glycerol. These processes involve different metabolic pathways.
