Aerobic respiration, occurring in the presence of oxygen, releases a significantly greater amount of energy compared to anaerobic respiration. It involves the breakdown of pyruvate in the mitochondria, producing carbon dioxide and water.
How does aerobic respiration differ from anaerobic respiration in terms of energy release?

Aerobic respiration and anaerobic respiration are two cellular processes that differ in their dependence on oxygen and the amount of energy released.
In aerobic respiration, which occurs in the presence of oxygen, glucose is completely oxidized in the mitochondria, yielding a maximum amount of energy through a series of complex biochemical reactions. The end products include carbon dioxide and water. Aerobic respiration is highly efficient, producing a large amount of ATP (adenosine triphosphate), the energy currency of cells.
On the other hand, anaerobic respiration takes place in the absence or limited presence of oxygen. While it allows cells to produce ATP without oxygen, the process is less efficient than aerobic respiration. In anaerobic respiration, only a partial breakdown of glucose occurs, leading to the production of lactic acid or alcohol, depending on the organism. As a result, anaerobic respiration releases less energy compared to aerobic respiration.
