Which of the following statement about cellular energyharvesting pathway is incorrect?
1 Pyruvate oxidation can only occur under aerobic conditions.
2 Autotrophs can produce their own food but must obtain energy from it by glycolysis & cellular respiration.
3 Fermentation usually occurs under aerobic conditions.
4 All of the above
Explanation:
(c) Fermentation represents anaerobic mode of respiration. In fermentation the incomplete oxidation of glucose is achieved by sets of reactions where pyruvic acid is converted to $\text{C}{{\text{O}}_{2}}$ and ethanol.
