Detailed explanation-1: -Muscle cells can continue to produce ATP when oxygen runs low using lactic acid fermentation. However, this often results in muscle fatigue and pain. Many yeast use alcoholic fermentation to produce ethanol.

Detailed explanation-2: -4: Lactic acid fermentation makes ATP in the absence of oxygen by converting glucose to lactic acid (through a pyruvate intermediate). Making lactic acid from pyruvate oxidizes NADH, regenerating NAD+ so that glycolysis can continue to make more ATP rapidly.

Detailed explanation-3: -A lack of oxygen inside of the muscle cells resulted in lactic acid fermentation. This is due to the cell needing oxygen as a terminal electron acceptor to produce ATP. Without oxygen present, the cells needed to create energy through a different method. Lactic acid, or lactate and H+ were created as a byproduct.

Detailed explanation-4: -Fermentation does not require oxygen and is therefore anaerobic. Fermentation will replenish NAD+ from the NADH + H+ produced in glycolysis.

Detailed explanation-5: -Lactic acid fermentation happens in the skeletal muscles. Pyruvate is converted to lactic acid by lactate dehydrogenase when oxygen is inadequate. Fatigue is brought on by lactic acid buildup in the muscles. It is a sort of anaerobic fermentation that takes place in bacterial and animal cells, such as muscle cells.
