During glycolysis, glucose is broken down to produce energy in the form of ATP. This process also produces pyruvate. In the presence of oxygen, pyruvate can be further broken down in the mitochondria to produce more ATP in a process called aerobic respiration.

However, in the absence of oxygen, pyruvate cannot be further broken down in the mitochondria. Instead, it undergoes a process called fermentation to regenerate NAD+, which is needed for glycolysis to continue. The products of fermentation (such as lactic acid in muscle cells or ethanol in yeast) are essentially waste products, but the regeneration of NAD+ is crucial for the cell to continue producing ATP in the absence of oxygen.

So, fermentation products are made during glycolysis to regenerate NAD+ and allow energy production to continue when oxygen is not available.
