Please answer the following question please!

Some bacteria can use fermentation (F) or aerobic respiration (AR) for making ATP. Describe the four most significant differences between fermentation and aerobic respiration. (Label them Diff#1, Diff#2, Diff#3, and Diff#4). Of those four, which is the most significant? Why do you think that?

Please answer to the fullest of your abilities!

Solution

1. Fermentation is an anaerobic process carried out in absence of oxygen. Aerobic respiration takes place in presence of oxygen.

2. The number of ATP produced during germentation are less ( 2 ATP from glycolysis) and ATPproduced from aerobic respiration are 30.

3. The end product of fermentation is carboxylc acid such as lactic acid or alcohol such as ethanol and CO₂. The end product of aerobic respiration is CO₂, water and ATP.

4. Citric acid cylce, electron transport chain (ETC) and Oxidative phosphorylation are absent in fermentation and occur in aerobic respiration.

5. Glycolysis is common both in fermentation and aerobic respiration. The end product of glycolysis, the pyruvate is converted to produce lactic acid or ethanol during fermentation. Pyruvate is oxidized to acetyl CoA to enter into citric acid cycle in aerobic respiration.

6. The most significant part of both fermentation and aerobic respiration is end productsand number of ATP produced.
