Which one of the following processes releases a carbon dioxide molecule?
Correct answer: B. Alcohol fermentation
- A. Lactic acid fermentation
- B. Alcohol fermentation
- C. Glycolysis
- D. Hydrolysis of glycogen
Explanation
In the absence of oxygen (anaerobic conditions), pyruvic acid accepts hydrogen atoms from NADH, forming lactic acid in a process called lactic acid fermentation. This allows glycolysis to continue, generating a small amount of ATP in the absence of oxygen.
