Which of the following reactions does not release CO 2 ?
Options
- AAlcohol fermentation
- BAerobic respiration
- CLactic acid fermentation
- DAmphibolic pathway
Correct answer
C. Lactic acid fermentation
Step-by-step solution
In lactic acid fermentation, C O 2 is not released, as there is no step of decarboxylation unlike alcohol fermentation. The alcohol fermentation includes the decarboxylation of pyruvic acid to Acetaldehyde, which is further reduced to ethanol due to the reducing agent NADH (which gets oxidized to NAD + . Aerobic respiration (amphibolic pathway) releases CO 2 due to oxidative decarboxylation of pyruvic acid to Acetyl-CoA.
