Aerobic and anaerobic respiration: How is glucose used and lactic acid produced?
Anaerobic respiration
Fermentation and anaerobic respiration do not require oxygen, but there are other references that consider that they are two different processes
Anaerobic is a method of cellular respiration that does not require oxygen to generate energy.
Fermentation serves as a final electron acceptor. This procedure produces lactic acid instead of carbon dioxide and water, so this type of respiration is only used for short intervals.
Anaerobic cellular respiration is quite similar to aerobic cellular respiration because in both of them electrons are transferred through an electron transport chain generated from a fuel molecule, accelerating ATP synthesis.
Anaerobic respiration is glycolysis, in which one molecule of glucose is broken down into two molecules of pyruvate, releasing electrons in the process and producing two molecules of ATP, the cells' energy.
Glucose is broken down without the presence of oxygen in anaerobic respiration. In fermentation, the end product can be lactic acid or ethanol. Apart from these substances, energy is also produced in the form of ATP molecules.

Why do muscle cells use lactic acid fermentation?
This acid serves as a preservative agent and as a flavoring substance in many food products at the same time.
Lactate allows the body to continue the breakdown of glucose and thus the production of energy.
Lactic acid in muscle cells is converted back to pyruvate in a well-oxygenated cell
Lactic acid is important for athletes because it
reduces the pH of muscle fibers and slows down the chemical reactions responsible for generating energy.
Muscle cells can produce lactic acid to give energy during difficult physical activities. it normally happens when there is not enough oxygen in the body.
Why Does Lactic Acid Build Up in Muscles? And Why Does It Cause Soreness?
A side effect of high lactate levels is an increase in the acidity of the muscle cells, along with disruptions of other metabolites.
Lactic acid is not responsible for the muscle soreness felt in the days after having a hard session of exercise. What really causes this burning sensation in our muscles is the production of lactate and other metabolites.
Our muscles create anerobical energy which is a kind of energy that comes from glucose through a process called glycolysis.
Anti-inflammatory drugs which reduce the muscle soreness may have good and negative things a good they may slow the ability of the muscle to repair the damage, but by this same goos thing it may have negative consequences for muscle function in the weeks following the strenuous event.
