Fermentation reactions primarily serve to regenerate NAD+ from NADH, allowing glycolysis to continue in the absence of oxygen by providing the necessary electron carriers. This process does not directly produce ATP (that's the role of glycolysis and oxidative phosphorylation), nor does it directly prepare pyruvate for the Krebs cycle, produce building blocks for biological molecules, or aim to provide products useful for humans, although some fermentation products are indeed useful.
