What is the difference between aerobic and anaerobic processes

The principle difference between aerobic and anaerobic process is aerobic process requires oxygen and generate more energy whereas anaerobic process occurs in absence of oxygen and generate less energy.

Explanation:

Aerobic process or aerobic respiration include glycolysis, TCA cycle and oxidative phosphorylation. As a result during Aerobic respiration a glucose molecule undergo complete oxidation to form CO2 and H2O along with 38 molecules of ATP.

On the other hand Anaerobic process or Aerobic respiration only involves glycolysis. As a result no TCA cycle and oxidative phosphorylation occur during Anaerobic process. Glycolysis that occur during Anaerobic produces only two molecules of ATP.

During anaerobic respiration the end product of pyruvate undergo lactic acid fermentation to form as well as to regenerate NAD+.

The process that requires oxygen is called an aerobic process while a process that doesn't air is called anaerobic process.

Explanation:

Processes in nature are aerobic and anaerobic. For anaerobic processes, air is not an essential element while it is not so for aerobic processes. There are several examples of aerobic and anaerobic processes in nature. Respiration, an important biological process sometimes takes place anaerobically in some organisms while most of the organisms respire aerobically.

Some bacteria can respire anaerobically. When organisms like yeast respire anaerobically alcohol and carbon dioxide is released.
