Answer:
Aerobic respiration is the process by which organisms use oxygen to turn fuel, such as fats and sugars, into chemical energy while Anaerobic respiration is respiration using electron acceptors other than molecular oxygen.
Explanation:
Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. The overall reaction is: C6H12O6 + 6O2 yields 6CO2 + 6H2O + energy (as ATP)
An example is respiration in humans.
Anaerobic respiration: In aerobic organisms undergoing respiration, electrons are shuttled to an electron transport chain, and the final electron acceptor is oxygen. Molecular oxygen is a high-energy [2] oxidizing agent and, therefore, is an excellent electron acceptor. In anaerobes, other less-oxidizing substances such as nitrate (NO3−), fumarate, sulphate (SO42−), or sulphur (S) are used. These terminal electron acceptors have smaller reduction potentials than O2, meaning that less energy is released per oxidized molecule. Therefore, anaerobic respiration is less efficient than aerobic.
Example: In anaerobic respiration, the process occurs in the absence of oxygen such as alcohol fermentation, lactic acid fermentation (which can result in yogurt and in sore muscles), and in decomposition of organic matter.
