Explanation

The end product of anaerobic respiration in humans and other mammals is lactic acid. In the absence of sufficient oxygen, cells resort to anaerobic respiration to generate energy. Anaerobic respiration involves the incomplete breakdown of glucose and results in the production of lactic acid as a byproduct. The specific process is known as lactic acid fermentation. During this process, pyruvate, which is an intermediate product of glycolysis, is converted into lactic acid. This reaction helps to regenerate NAD+ from NADH, allowing glycolysis to continue in the absence of oxygen.
