What are the two common end production for anaerobic respiration?

The two common end products of anaerobic respiration are:

1. Lactic acid: This is the end product of anaerobic respiration in muscles when the body is under stress and oxygen supply is limited. The accumulation of lactic acid can cause muscle fatigue and soreness.

2. Ethanol (Alcohol): This is the end product of anaerobic respiration in yeast during the process of fermentation. It is a commercially important product used in the production of alcoholic beverages. Ethanol can also be used as a fuel source.
