What is the fermentation equation for animal cells?

The fermentation equation for animal cells, specifically lactic acid fermentation, is represented as:

[ \text{Glucose} \rightarrow 2 \text{Lactic Acid} + 2 \text{ATP} ]

In this process, glucose is converted into lactic acid in the absence of oxygen, producing a net gain of two ATP molecules for energy. This type of fermentation occurs in muscle cells during intense exercise when oxygen is scarce.
