Anaerobic respiration is a process that occurs in animals and plants when there is a lack of oxygen. Itis a backup plan for respiration when the oxygen supply is limited. In anaerobic respiration, glucose is
broken down directly without the involvement of oxygen. This process is less efficient than aerobic
respiration and produces much less energy.
Lactic acid in anaerobic respiration is to temporarily convert pyruvate, the end product of glycolysis,
into a usable form of energy in the absence of oxygen.
● Lactic acid allows the continuation of energy production when the oxygen supply is limited, such
as during intense exercise or when the heart and lungs cannot keep up with the oxygen demand.
However, lactic acid is a byproduct of anaerobic respiration and can build up in the muscles,
causing muscle cramps and fatigue.
There are several ways to eliminate lactic acid from the body. One way is to take in oxygen again, which
helps break down lactic acid into carbon dioxide and water through aerobic respiration.
● Another way is to engage in low-intensity exercise or perform light stretching, which helps to
increase blood flow and remove lactic acid from the muscles. Additionally, staying hydrated and
consuming foods rich in antioxidants can also aid in the elimination of lactic acid.
Oxygen is needed in the breakdown of lactic acid because it is involved in the process of aerobic
respiration. During aerobic respiration, oxygen helps to break down lactic acid into carbon dioxide and
water, releasing energy in the process.
● This is a more efficient way of producing energy compared to anaerobic respiration, which
produces lactic acid as a byproduct. The breakdown of lactic acid with the help of oxygen allows
the body to eliminate lactic acid buildup and prevent muscle cramps.
HOW DOES ANAEROBIC RESPIRATION WORK IN ANIMALS
Anaerobic respiration in animals occurs when the heart and lungs cannot supply enough oxygen to
meet the body's demands. In this process, glucose is partially broken down without the involvement of
oxygen, resulting in the production of lactic acid as a byproduct.
● This type of respiration is less efficient than aerobic respiration and produces less energy.
However, it serves as a backup plan when oxygen is limited. The buildup of lactic acid can cause
muscle cramps, which can be relieved by taking in oxygen again to break down the lactic acid
into carbon dioxide and water.
HOW DOES ANAEROBIC RESPIRATION WORK IN HUMANS
Anaerobic respiration in humans occurs when the demand for oxygen exceeds the supply, such as
during intense exercise. In this process, glucose is broken down directly without the involvement of
oxygen, resulting in the production of lactic acid as a byproduct. This type of respiration is less efficient
than aerobic respiration and produces less energy.
● This type of respiration is less efficient than aerobic respiration and produces less energy. Lactic
acid buildup can cause muscle cramps. To get rid of lactic acid, oxygen needs to be taken in
again, which replaces the oxygen debt. It is important to note that anaerobic respiration is a
backup plan when the body cannot meet its oxygen demands.
