ATP is the source of enery. Aerobic is when organisms that need air or oxygenn to produce energy to breathe and anaerobic is just the opposite of that. :) Your welcome. :)

They are pretty much the same in terms of HOW it is done, but WHAT molecules and enzymes are involved differ. For example, in anaerobic respiration (found in many prokaryotes), there is an electron transport chain (just like in aerobic respiration) and the electron donor is organic (just like in aerobic respiration).

The main differences lie in the amount of ATP produced (25; less than aerobic respiration, which produces ~36-38) and, of course, differing final electron acceptors. In anaerobic respiration, O2 will NOT be the final electron acceptor (hence the name) ... various final electron acceptors are used

well in animal or plant cells generally a "respiratory substrate" or something like glucose is oxidized or simply broken down to make ATP,In the cytoplasm of any cell,plant or animal glycolysis will occur giving out 2 ATP and forming 2 Pyruvate molecules.

Depending on the prescence of Oxygen(aerobic) or its' abscence(anaerobic) the the fate of the Pyruvate molecule can be decided.

In aerobic respiration the pyruvate formed will proceed with the Krebs cycle and Electron Transport chain and form 36 or 38 ATP..

In anaerobic respiration in plants ethyl alcohol would be fermented along with carbon dioxide n 2 ATP,and in animals lactic acid will be formed along with 2 ATP...

Though the numbers look widely different in comparison the energy conversion efficiency in Aerobic respiration (roughly 40.3%) and lactic acid fermentation (roughly 40.8%) is close.That is why anaerobic lactic acid fermentation is favoured in humans during strenous exercise when oxygen levels dwindle..

I hope you got your answer..good luck with your studies
