Difference between aerobic and anaerobic respiration - theme
Aerobic and anaerobic respiration are types of cellular respiration, the process by which living cells use up the free electrons produced during normal cellular metabolism to produce ATP, or adenosine triphosphate, the chemical compound used by cells for energy. Aerobic and anaerobic respiration differ in their requirement of oxygen and the amount of energy they produce, as well as which organisms they are utilized most often in and why. Aerobic respiration can only occur in the presence of oxygen, while anaerobic respiration doesn't require or utilize oxygen in its energy production. In aerobic respiration, glucose molecules are passed through a chemical reaction chain that produces ATP, carbon dioxide and water and ends with oxygen accepting the free electrons that have been generated. In contrast, anaerobic respiration is cellular respiration that occurs using other molecules as the terminal electron acceptor since oxygen isn't present. Both aerobic and anaerobic respiration use electron-transport chain-reaction pathways in energy production. However, aerobic respiration produces much more energy, or ATP molecules, than anaerobic respiration. For every molecule of glucose that is metabolized in the presence of oxygen by aerobic respiration, 38 ATP molecules are produced.Difference between aerobic and anaerobic respiration - think, that
The first step of aerobic respiration glycolysis takes place in cytoplasm while the next step takes place in mitochondria. Even in anaerobic respiration, the first step takes place in cytoplasm while the next step takes place in mitochondria. The process of anaerobic respiration takes place in lower organism like yeast, some species of bacteria and parasites like tapeworm. What are the differences between aerobic and anaerobic respiration. Name some organisms that use the anaerobic mode of respiration. Best Answer Ans:Aerobic respiration i. The process takes place in the presence of free oxygen ii. The products of aerobic respiration are CO2, water and energy. The process of aerobic respiration takes place in all higher organisms.

While studying respiration, I came across a line in one book that anaerobic respiration is different from fermentation in the fact that the final electron acceptor in the electron transport chain in case of anaerobic respiration is any inorganic molecule other than oxygen wheres in case of fermentation it is an organic molecule. Then again it is written that since anaerobic respiration involves incomplete oxidation of glucose so the amount of energy released is way less than that released in case of aerobic respiration.
In the following article it is mentioned that anaerobic respiration proceeds in a similar manner like aerobic respiration i. If that is indeed the case, then why does anaerobic respiration give off less energy than aerobic respiration when the only difference is in the nature of the final electron acceptor?

The fundamental answer is that the energy released transferring electrons to other elements is less than the energy released transferring electrons to O2. Since not as much energy can be released here, not as many ATP molecules can be produced. The electron transport chain is structured just a little differently reducing the numbers of protons pumped per pair of electrons differennce NADH and so less ATP can be produced.
