Because fermentation does not require oxygen
Fermentation is carried out, most commonly by single celled organisms to generate energy from the breakdown of organic molecules. It is an anaerobic metabolic process because it cannot take place in the presence of oxygen. This would require an aerobic metabolic process that utilizes oxygen.
Anaerobic pathways are metabolic processes that occur in the absence of oxygen, allowing organisms to generate energy. These pathways primarily include fermentation, where glucose is partially broken down to produce ATP and byproducts like lactic acid or ethanol. Anaerobic respiration also involves using electron acceptors other than oxygen, such as nitrate or sulfate, to facilitate energy production. These pathways are crucial for certain microorganisms and tissues, especially when oxygen is scarce.
Anaerobic by-products, such as lactic acid or ethanol, can be further metabolized in processes like fermentation or converted into other substances by other biochemical pathways. In the case of lactic acid, it can be converted back to pyruvate and metabolized in aerobic conditions. Ethanol produced during anaerobic fermentation can be used in various industrial processes or as a biofuel.
Anaerobic species are organisms that thrive in environments without oxygen and typically rely on fermentation or anaerobic respiration for energy. Characteristics of anaerobic species include the inability to utilize oxygen for growth, the production of energy through fermentation pathways, and often the ability to survive in extreme environments. A characteristic that is not typical of anaerobic species would be the requirement of oxygen for growth or metabolism, as this would classify them as aerobic organisms instead.
The two pathways of respiration are aerobic respiration and anaerobic respiration. Aerobic respiration occurs in the presence of oxygen and produces more ATP, while anaerobic respiration occurs in the absence of oxygen and produces less ATP.
You must learn terminology. The word anaerobic means without oxygen. They do not or can not use oxygen. The reaction that doesn't use oxygen produces less energy than ones that can use oxygen.
Under anaerobic conditions, NAD can be recycled through fermentation processes that regenerate NAD+ from NADH. This allows cells to continue glycolysis and produce ATP in the absence of oxygen. Fermentation pathways, such as lactic acid fermentation or alcohol fermentation, are utilized to regenerate NAD for these anaerobic processes.

The processes of glycolysis and anaerobic pathways are collectively referred to as fermentation. This metabolic process helps cells generate energy in the absence of oxygen by breaking down glucose into smaller molecules.
Fermentation is anaerobic respiration. Glycolysis is part of aerobic respiration. The pathways for both processes, however, are almost identical to each other.
Fermentation occurs when a cell does not get enough oxygen to carry out aerobic respiration. Instead, the cell uses anaerobic pathways to produce energy in the form of ATP.

Two pathways that might follow glycolysis are aerobic respiration and fermentation. In aerobic respiration, pyruvate is further broken down in the presence of oxygen to produce more ATP. In fermentation, pyruvate is converted into different byproducts (such as lactic acid or ethanol) in the absence of oxygen, generating a small amount of ATP.
