Which of the following statement is correct?
1. Glycolysis is present in facultative anaerobes, not in obligate anaerobes
2. Usually carbohydrates are oxidised to release energy in cellular respiration
3. Oxidation of one molecule of NADH gives rise to 3 molecules of ATP in anaerobic respiration
4. Fermentation takes place under anaerobic conditions in prokaryotes only
ln ETS the number of ATP molecules synthesized depends on
1
2 Substrate
3 Electron donor
4 Proton gradient

1 Only c is incorrect
2 b & d are correct
3 c & d are incorrect
4 Only b is correct
