Anaerobic respiration is a process where the breakdown of pyruvate occurs in the absence of air (oxygen). It takes place in organisms like yeast during fermentation.

Anaerobic respiration is a metabolic process where the breakdown of glucose occurs in the absence of oxygen. This process aims to generate energy in the form of ATP without the involvement of molecular oxygen. Anaerobic respiration typically occurs when oxygen availability is limited or absent, such as during intense physical activity when oxygen demand surpasses supply. In the absence of oxygen, organisms resort to anaerobic pathways like lactic acid fermentation or alcoholic fermentation, depending on the organism. While anaerobic respiration is less efficient in terms of ATP production compared to aerobic respiration, it provides a rapid means of energy release when oxygen is scarce.
