NEET BIOLOGY

Detailed explanation-1: -Your liver and kidneys filter lactic acid out of your blood and break it down into glucose (blood sugar).

Detailed explanation-2: -After running you continue to breathe quickly. The extra oxygen you breathe in reacts with the lactic acid in your muscles, breaking it down to make carbon dioxide and water.

Detailed explanation-3: -Alternatively, the liver can break down lactic acid by reacting it with oxygen to produce carbon dioxide and water, which you might have noticed are the same products as aerobic respiration. The amount of additional oxygen that is necessary to remove lactic acid from the body is called oxygen debt.

Detailed explanation-4: -When the body has plenty of oxygen, pyruvate is shuttled to an aerobic pathway to be further broken down for more energy. But when oxygen is limited, the body temporarily converts pyruvate into a substance called lactate, which allows glucose breakdown-and thus energy production-to continue.
