Which compound is associated with a burning sensation as a result of anaerobic respiration?

Carbon dioxide is a byproduct of aerobic respiration and does not directly cause a burning sensation. While it accumulates in the body during intense exercise, it is more associated with the feeling of breathlessness rather than the localized burning sensation linked to lactic acid.

Oxygen is essential for aerobic respiration and is not involved in the production of lactic acid. It helps to prevent the buildup of lactic acid by allowing for complete glucose oxidation. Therefore, oxygen itself does not cause any burning sensation associated with anaerobic respiration.

Glucose is the substrate that undergoes metabolism during both aerobic and anaerobic respiration. While it is crucial for energy production, it does not directly cause the burning sensation. Instead, the breakdown of glucose in the absence of oxygen leads to the production of lactic acid, which is the actual cause of the burning feeling.
