Explain - Anaerobic Respiration in muscles.
Answers
Answer:
Anaerobic respiration in muscles - Sometimes muscles of human beings can respire without oxygen. This generally happens when we undergo a heavy exercise such as running, weightlifting, cycling or walking for a longer duration. In such situations, the muscles require more energy and the supply of oxygen is not enough. Hence anaerobic respiration takes place in the muscles. As a result, muscles produce lactic acid along with energy. This lactic acid accumulates in the muscles and causes cramps. In order to get relief from cramps, we can take a hot water bath or massage our muscles which improve the blood circulation in the muscles. As a result, the oxygen reaches the cells easily which breaks on the lactic acid into carbon dioxide and water.
Anaerobic Respiration in muscles occurs due to insufficient amount of Oxygen to breakdown Pyruvate and make ATP energy but due to insufficient amount of Oxygen it only makes 2 ATP of energy , thus it makes lactic acid in the muscles and is the main cause of cramps .
